Graphene Conducts Electricity Ten Times Better Than Expected
ananyo writes "Physicists have produced nanoribbons of graphene — the single-atom-thick carbon — that conduct electrons better than theory predicted even for the most idealized form of the material (abstract). The finding could help graphene realize its promise in high-end electronics, where researchers have long hoped it could outperform traditional materials such as silicon. In graphene, electrons can move faster than in any other material at room temperature. But techniques that cut sheets of graphene into the narrow ribbons needed to form wires of a nano-scale circuit leave ragged edges, which disrupt the electron flow. Now a team led by physicist Walt de Heer at the Georgia Institute of Technology in Atlanta has made ribbons that conduct electric charges for more than 10 micrometres without meeting resistance — 1,000 times farther than in typical graphene nanoribbons. The ribbons made by de Heer's team in fact conduct electrons ten times better than standard theories of electron transport they should, say the authors."

On February 5, 2014, Slashdot announced through a javascript popup that they are starting to "move in to" the new Slashdot Beta design. Slashdot Beta is a trend-following attempt to give Slashdot a fresh look, an approach that has led to less space for text and an abandonment of the traditional Slashdot look. Much worse than that, Slashdot Beta fundamentally breaks the classic Slashdot discussion and moderation system.
If you haven't seen Slashdot Beta already, open this in a new tab. After seeing that, click here to return to classic Slashdot.
We should boycott stories and only discuss the abomination that is Slashdot Beta until Dice abandons the project.
We should boycott slashdot entirely during the week of Feb 10 to Feb 17 as part of the wider slashcott

Whatever is going on around here was predicted a long time ago.
See the news from the time.
Captcha - "Predict"
I will keep repeating this until Beta is gone, no matter how many times you'll downmod.
Nobody buys Playboy for the articles. They do it for the hot, nude women (sadly, sans grits). It just so happens that /. is exactly the same. No one reads /. for the articles. The articles were news two days ago. And no one reads /. for the summaries. The summaries are almost always wrong.
Everyone reads /. for the comments. The comments are the /. equivalent of Playboy's naked chicks, with one crucial difference. Without the gentlemen at Playboy, there will be no naked chicks to look at. The service they provide is, for the most part, finding women that will agree to pose nude for pictures, which they most graciously distribute to their readers.
But as for Slashdot -- the good people at Dice and their "editorial" team do diddly squat around here to generate content. The articles, old as they may be, are submitted by the users. The summaries, mistaken as they may be, are provided by the users, not by Timothy, Soulskill, et al. The comments, trollish as they may be, are written by the users.
/. is of the users, by the users, for the users. The only people at Dice who deserve their paycheck are the IT people. The rest of you -- what is it that you do for our benefit? Why the hell do we need you clowns? Your music's bad and you should feel bad!
Beta delenda est!
It is now official. Netcraft has confirmed: Slashdot is dying.
One more crippling bombshell hit the already beleaguered Slashdot community when IDC confirmed that Slashdot page views has dropped yet again, now down to less than a fraction of 1 percent of all websites. Coming on the heels of a recent Netcraft survey which plainly states that Slashdot has lost more market share, this news serves to reinforce what we've known all along. Slashdot is collapsing in complete disarray, as fittingly exemplified by the stupid fucking beta website and the wholesale discard of user feedback with only a token attempt at communication.
You don't need to be the Amazing Kreskin to predict Slashdot's future. The hand writing is on the wall: Slashdot faces a bleak future. In fact there won't be any future at all for Slashdot because Slashdot is dying. Things are looking very bad for Slashdot. As many of us are already aware, Slashdot continues to lose market share. Red ink flows like a river of blood.
Slashdot Beta is the most endangered of them all, having lost 93% of its core users. The sudden and unpleasant departures of long time Slashdot users Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: Slashdot is dying.
All major surveys show that Slashdot has steadily declined in market share. Slashdot is very sick and its long term survival prospects are very dim. If Slashdot is to survive at all it will be among S&M enthusiasts. Slashdot continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, Slashdot is dead.
That crippling bombshell sent Slashdot fans into a tailspin of mourning and denial. However, bad news poured in like a river of water.
Your contributors (not audience) are giving you a clear message.
... Beta sucked so much!!
Apparently carbon isn't very good at introspection...

Scientists discover that Beta conducts vapid corporate mentality better than theory predicted, even for the most idealised forms of Slashdot.
How soon before they can commercialize it to produce macroscopic wires that are used outside of an IC package?
Then produce big enough cables of wire to deliver electricity long distance?
And produce these wires economically?
I'll see your senator, and I'll raise you two judges.
We don't know that those predictions will come true. The fast majority of the F*ck Beta comments are coming from ACs. For all we know that could be a single individual or even a bot.
Slashdot has always had disgruntled people participate with it. But a lot of postings by an AC really are worthless to base anything on.
However, if slashdot dies because of this, it won't be because of Dice. It will be because like the dinosaurs, we couldn't adapt.
You must be new around here.
Precious.
The conductivity of graphene pales in comparison with Beta's ability to direct users away from Slashdot.
idiots. So i can't block google analytics or i get the "NANU NANU" shit? go fuck yourselves with a fork
Very much so and thanks for your contribution. DICE will not listen, but altslashdot.org will listen. The name is tentative but the goal is clear: community first.
Yeah, right, don't you mean community first until the community doesn't like something that owner/provider doesn't like?
If altslashdot.org users start posting porn, will that be acceptable? If they decide only whites or males should be allowed to post, will that be acceptable? The moment you post rules, you have dimminished community first, even if the community votes on them. Why? because future members of the community don't get a chance to vote on them, so really what you have is founders first, not community first.
I am skeptical about such an extraordinary claim.
Side note: Please, stop with the "fuck beta" campaign; I find this campaign FAR MORE DISRUPTIVE to the enjoyment of /. than the beta itself. Get over Yourselves already.
derp beta derpa
While it is interesting to see the advances with graphene, if used to make super fast computers, isn't the "wiring" on the chip only a small part of the problem? Have they found a way to make the transistors and resistors and parts on the chip out of graphene? If not, wouldn't the speed improvements be nonexistent? It would seem that it would be like taking a super highway and bringing all the traffic down to one lane at the exits (or maybe a bridge in NJ).
It seems to work. OK for me. I see myself typing a comment. Perhaps you are just not smart enough to use something slightly different.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
please, new guy GTFO
why mess with what works and fans love. FUCK BETA
I feel the loss of the comment threads as much as you jellomizer. Which is exactly what this whole thing is about. The new site model nukes the existing message board structure.
Rather than see these as off topic posts, spamming the message boards, try the perspective that there is only one topic until this issue is resolved to the communities satisfaction and that these comments are in fact using the message boards for their intended purpose: maintaining a moderated discussion guided by the consensus generated by the readership.
These posts have become the most effective manner of communicating to the correct authority. The correct authority in this case is the broad readership, some of whom are just learning about this. The other authority is the controlling entities who have thus far made some poor choices about not responding to the communities posts in the designated channels. Therefore this is the next step in a spectrum of responses.
I personally apologize to you for the necessity of this step which has been provoked by the site operators. I do hope things change quickly, since I love slashdot. I am slashdot.
FORK->FORKFORK-FORK
For people who claim that science is wrong/bad/not complete - this is the kind of thing that research and study can do.
The expected result was off by 10x. This doesn't mean that science sucks - but rather there is a new question to be answered that will allow us to understand the world just a little bit better.
AWESOME.
When electricity is conducted on a wire,are new electrons sent down the wire riding on the surface? Or are they pushed through the mass of existing electrons and cause one currently in line to bounced off the back end (like a newton's cradle)? Something Ive always wondered...
It works almost exactly like a newton's cradle. The whole mass of metal atoms transfers its electrons through the whole wire. At least that is the theory that is accepted. "Electronics All-In-One Desk Reference For Dummies" is a good book for understanding how electricity works.
is wrong with the comment system here?
I've deliberately gone to beta to check it out, seems OK.
I think with this whole Beta flap we can all agree on two things.
First, SlashDot Beta sucks. OK - whatever, who gives a shit.
Second, Slashdot is infested with the most annoying, entitled, childish fucking little neckbeard cumstain dweebs on the Internet. Most of you fucking dolts make 4chan users look like Rhodes Scholars.
Technically most of you are stuck in 1978, just completely fucking clueless. You post the same repetitive, boring as _fuck_ "memes" (what a stupid fucking word). Your personal hygiene is atrocious and women don't like you because you're ugly as shit and your personality is terrible. It's not that she's shallow and won't love you because she doesn't know you, it's that you are a sub-par human being. I promise.
I think all the repetitive, boring posts being spammed by you fuckers concerning the beta seals the case. Shut the fuck up already, no serious person gives that much of a fuck. But that's the thing, I guess. None of you are serious people, just caricatures - cardboard cutouts of a stereotype regarding socially inept misfit losers.
Hey slashdot, keep the javascript-free version.
It's been decades since I took solid state physics courses, but here's what I remember.
Conducting solid, like metal, is modeled as a single monolithic entity as opposed to a set of individual elemental atoms. Each atom's high(est) energy electrons become "free" electrons that can move about the whole solid with minimum provocation (i.e., voltage). So when electric field or voltage is applied across the solid, these free electrons bunch up towards positive charge - i.e. the "skin" you referred to.
Because, you know, electrons have a negative charge. Haha.
So when voltage is applied to the solid, and there is a route out of the solid towards positive charge, the free electrons will move that way. If there is also a route into the solid through which new (to the solid) electrons move in, then you have a circuit where electrons flow in and out of the solid (as you say) along the skin, and hence you have current.
That's what I remember of the simple version of solid state model that look at solid's free electrons as a group. Because the free electrons are treated as a group, it doesn't deal with whether the electron that just popped out are new (to the solid) one or the last one in line - the model doesn't give individuality to each electrons.
Not sure it answers your question adequately, but that's what popped into my head. Maybe others will do a more proper job.
Like I was saying, KEEP THE JAVASCRIPT-FREE SLASHDOT, you dirtbags! :-)
Fuck systemd. Fuck Redhat. Fuck Soylent, too. Wait, scratch the last one.
That's very great news for graphene and everything that could be built out of it.
But didn't these results just invalidate a theory? Is there someone that is actually looking why the current theory fails to explain the observed behavior?
Talk to them in terms they can understand -- go to classic mode and continually click-through all of the ads. But given the track record of the UI, they are probably too dumb to see where the bump in the ad traffic is from.
In graphene, electrons can move faster than in any other material at room temperature.
Is it really a "new material?" Isn't it just 1 atom thick graphite? If I had a sheet of 1 atom thick silver... can I call it a new material, "silvene," and claim it is 100 times more conductive than any other material at an arbitrary temperature?
Is this article about graphene or as the comments suggest, about Beta?
The electrons are always moving, and fast, very fast, on all directions, with a zero average speed. Electrical current appears when their average velocity goes slightly above zero.
It's not one electron bouncing in another that causes the movement, all electrons are equaly pushed by a potential. Bouncing is one of the causes of resistivity. What this istudy did was reducing bouncing to the point it become negligible, with the expected impact on resistivity.
I hope that answers. It's like none of your options.
Rethinking email
And we expected it to be pretty bad.
Fuck beta.
Beta sucks
That that is is that that that that is not is not.

It will die down on its own eventually as people grow tired of yelling and not being heard. We don't live in an age in which protests are appreciated or encouraged anymore. Unfortunately, this will probably lead the powers to be behind the site design to believe that this meant it was just a vocal minority and that the majority of Slashdot is chill with the redesign or have "come around" on it. That will be wrong, but such self-delusion is inevitable.
There's obviously heavy personal investment in the time and energy (and money) in creating the new Beta site. It isn't going to go away, despite being a terrible idea, because the people behind it won't be able to admit for various personal and professional reasons that they've f'ed up royally. So, in their minds, they'll have to build a fortress of arguments to shore up their position. No doubt they're smart people, so they'll probably be really good at rationalization. In my professional experience, once people have started working on a design they helped create, they get very territorial and hard to move in new directions.
The end result is a train wreck we can all see coming. What people is the equivalent of yelling at someone on a screen not to go in the cabin in the woods where the killer is waiting. They know it isn't going to help, but it helps them deal with an unpleasant situation. The woman, like Slashdot, was dead the moment the scene started.
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
I am slashdot.
In a better analogy, you are one of the slashdot neurons. When enough of us leave (I'll be one of those) the slashdot "brain" will be only a rotting hulk of (Dicey) grey goo. Hint to Dice from Capt. Duh: You can generate revenue only if you have viewers - not a sufficient condition, but a necessary one.
I would imagine this would have an amazing benefit in the world of capacitors and batteries.
Always in beta,
Sensuous is classical,
broken so slashdot
using bold or italics ?

URL to a comment, I have no idea. I see how that'd be annoying.
Okay, so you have to use "em" for italics...
I wasn't going to join in the whinning but, what the hey.
Something something BETA dark side!
-- Counting backwards since 1984!
When I saw "than" used correctly in a sentence, I was taken aback. It has been a long time.
You mean sites like alternet.org ?
how quickly will this be implemented by the bicycle lighting folks?
...to lower the resistance to the Slashdot beta.
