Nanotech Brings Cheap Flat TVs From Diamond Dust
neutron_p writes "Nanotech scientists are going to develop new TV display technology made from diamond dust.

Nice spelling.

Diamonds... That'll shut her up... For a minute at least.
Slashdot is kind of like Playboy; we aren't here to read the articles.
Does it say something about the cost of electronics when it makes it cheaper to make them out of diamond dust?

This diamond television means I can now buy the expensive tv I've always wanted and call it an anniversary gift.
"But, honey, you said you wanted diamonds, right?"
The article has so little information! it describes nothing of the technology except that it's going to be worked on.
We should call Shiva!
Finally, men and women will be able to agree that buying a bigger one is a good idea.

How long until the AWK (Advanced Watchable and Karryable) and GREP (Graphics-Rendering Efficient Power) technologies come out?
Wired had a great article in the past about how the synthetic diamond industry is breaking through, which means that quality synthetic diamonds may soon be cheap to use for electronics purposes. (Real diamonds are more expensive just they are naturally made, but synthetics can be virtually indistinguishable quality-wise.)

Is this some kind of reference to Neal Stephenson's Age of Diamonds? The feed was the way nanotech was controlled by the Victorians, and the seed was the way to free it from that control... I know this is offtopic but a post about real nanotech mentioning SED vs FED was just... strange.

if my girlfriend would wear the diamond dust flat screen on her finger when I propose. It can display the diamond ring that I will eventually get for her after I invent the next nanotechnology breakthrough, using common household dust to make dirt cheap displays.
1. Make synthetic diamonds. This technology has been around since the 1950s and people seem to be getting closer to making it relatively cheap.
2. Drag a white dwarf into orbit and mine it. On second thought, that might be *more* expensive. Oh, well.
I know what you mean, but maybe you should have linked an image that actually showed the test or context - after all, Shiva's a name of a Hindu god.

Naaa, neutron_p just speaks with a lisp.
Diamonds aren't rare. In fact, there are more jewel-grade diamonds of large size and high quality than there are people.
The diamond industry works entirely off of the perception in most people that diamonds are rare. They strictly limit the supply, and spend more money advertising than they do mining.
If you don't believe me, take a piece of diamond jewelry to several jewelers and have it appraised. They'll all quote a fairly large sum. Now try to sell it to them. They'll offer you maybe 5-10% of what they quoted.
If you shop around, you'll find that you can't actually sell a diamond for anywhere near what it's "worth."
That said, synthetic diamonds scare the living hell out of the diamond industry, since they're cheap to manufacture and indistinguishable physically from a "real" diamond (which itself isn't rare, but I digress).
These displays will drive more research and capital into the diamond manufacturing market, which will drive diamond prices down.

Or titmouse. It goes back to a Cheech and Chong movie. I forget which because of the weed. But in the totally-reenginnered PC TV version, they changed all the coke or pot references to 'diamond dust.' There's plenty of staccato scenes with huge chunks missing and lots of quotes like 'Yo, pass the DIAMOND DUST.' 'This is some excellent DIAMOND DUST!' 'Let's snort up some of this DIAMOND DUST.' And diamond dust is voiced in a totally different monotone white guy's voice. I will never feel the same about DIAMOND DUST ever again.

Macadamia nuts are cheap too.. the trouble is getting them out of their shells without crushing them. Most of the nuts get broken in the de-shelling machine, and as a result, macadamia nut chunks for use in baking sell for a lot less than the same mass of whole nuts. There's a small fortune waiting for someone who commercializes an industrial-scale nutcracker that really works on macadamias.
Diamonds, she'll pretty much have to.
I'm building one out of Legos to sit next to my grandfather clock and 3-D chocolate printer.
Nanotech is certainly one of the most promising ideas being thrown around today. If only they'll find a way to make it cheaper!
Imagine being able to write on a whiteboard, and then "save" it to disk. The pens would never run out of ink, you could scroll stuff out of the way when you don't need it anymore... Just in producing a completely "dry" whiteboard, which is actually a write-on computer display like those tablet PCs, I can see a tremendous use for a "cheap flat TV." This would help university students tremendously. I find that students often spend so much time writing notes that they don't allow the information to "sink in" properly. The other problem with notes is that they are static. Imagine if they could just sit in class and absorb everything, then receive what was written on the board by email. To make this even more useful, the whiteboard would be saved as a video, instead of as a static image, so that they could see in what order things were written. For math and the like, this would be especially innovative.
I can't wait until nanotech, display technology, and flexible circuits reach such high production and low cost volumes that all the books will be "printed" with pages made of them.
Imagine opening a book and being able to animate the illustrations therein... But what am I talking about? That's at least 50 years off. :-) "Like radio with pictures..."
Think of it this way. The heaviest half of the moon points toward Earth. The same phenomenon doesn't happen with the Sun, because the Sun is primarily a fluid.
Why yes, I AM a rocket scientist!
If the earth was trying to sping enough faster (or slower; it's all relative) than the orbital period, then things on the ground would move over this "hump" very quickly, and might be thrown into the air, much like a car going too fast over a hill. If this happened on the hump pointing towards the dwarf (there'd also be one pointing away from it), then any people who got "launched" in this manner would stand a decent chance of being captured by the gravity of the dwarf, and landing on it. They would then become the richest people in the solar system, unless someone else had claimed the dwarf first.

The moon is smaller and therefore is easier/faster to stop. Give the earth enough time and it too will be locked with one side facing the sun.
I read the diamond dust article at NanoInvestor News, and frankly it still seems mid to long term.
If you want a WORKING flat display, check this out this experimental flat display (picture) using carbon nanotubes as the electron emission source. I just glimpsed over it, but I think this was done by Motorola. At least, the dates fit (2003).
Recently, Samsung's Korean research achieved the same goal, and apparently they're ready for mass production. I told this in an earlier post elsewhere. They plan to distribute their nanodisplays around 2006.
Here's a PDF about Samsung's nanotech displays.
(Unfortunately for me, on the very same day, some guy posted a story about a _DIFFERENT_ kind of "ultra-flat" displays, also by Samsung, that would be available in 2005. I guess the mods confused the articles - bad luck, heh).
Anyway, the diamond dust tech seems too young for now. Samsung's nanotube displays already exist (at least experimentally).
The original statement about nanotech and dust just got me thinking about something that I hadn't considered before. Namely, has anyone ever studied the dust which results from objects created by nanotech? The reason why I'm wondering about this is due to two recent reports from the past year. The first mentioned that nanotech particles could accumulate within the brain. Sort of like a poisoning effect. The second report was about dust from computer devices made with a flame retardant; the result of which was that the chemical associated with the retardant accumulated in the body as well.
I'm wondering if we'll see a similar report about nanotech dust. Yeesh.
Does anyone know if any research has actually looked at this? Or has this thought been completely missed?
1) Grind up 20 pounds of diamonds ...errr profit?

Real diamonds ARE more expensice. The reason they are more expensive has nothing to do with his point.

There's plenty of Diamond Dust that comes off of diamonds used to make jewelry. They gotta inspect the diamond then cut it to its shape. There's gotta be some useable dust there.

Once again, the physorg honeypot grabs slashdot eyeballs. Physorg takes press releases and puts them up, with bad formatting, on ugly web pages... with no links to the original source.
:) It's also, um, not exactly what I'd call "nanotech"... unless you consider any product involving structures at the molecular scale (like, oh, wood, or portland cement) to be "nanotech".
So here's some missing links: the press release at Bristol, the diamond group at bristol and the home page of Advance Nanotech.
As you can see, that's a chemical vapor deposition group, so there's no need to grind up diamond dust from real diamonds.

You are talking about layers that are sub-micron in thickness, often less than 100 nanometers. A one micron thick layer on a meter-square screen is 10-6 m^3, or a cm^3. Therefore, you would need 1-2g of whatever substance you are talking about. Even the most exotic research-grade chemicals rarely cost more than $100/g, or $100 to $200 per screen. In reality, the cost would be much less for anything a production scale - $10/g at most, or $10-20 per screen. The raw material cost is dwarfed by the processing cost. On another point, does anyone know how nano-diamond is synthesized and in what quantity it can currently be done? I didn't find the answer with a quick web search, though I didn't look in the literature at all. The other half of my research group is now synthesizing nano-sapphire (alpha alumina). Pretty interesting stuff, actually, especially if you ever see the machine in operation. They call it "Smaug" for a reason.
That PDF article's pretty good, but I think they've got it wrong about burn-in problems with CRTs and the FE displays. Burn-in has always been a problem with CRTs. Just look at any old ATM or information kiosk. Phosphor coatings have well known burn-in issues. Surely FE displays, with effectively the same technology at the glass side would have the same problems.
One of these days I'm moving to Theory - everything works there

Apparently you don't realize that when perfectly made commerrcial diamonds are commonplace, then natural diamonds with all their imperfections will become worth much more as a result, because of their natural imperfectness.
And then eventually...
someone will start making paste "natural" diamonds.
Once the electron is excited to the higher state equalling the difference between the bandgap (5.5 eV) and the NEA value (which is 2.4 eV on hydrogen saturated surfaces) , the electron just flies out of the material instead of becoming delocalized into the crystal.
I'd have thought it would be "An electron in the 5.5v conduction band would be ejected from the crystal with a momentum equaling the difference between the conduction band and electron affinity voltages."
Very sweet if that's the mechanism.
Given that they mentioned "field emission", though, there might be a simpler mechanism.
Field emission is essentially the same thing in a vacuum as a corona discharge is in a gas. If you have a pointed electrode near a broader conducting surface (like a plate or a ring) with a voltage between them, the electric field strength (volts per unit length) is extremely high near the tip of the pointy electrode and falls off as you approach the broad one.
In a gas, the field is enough to ionize the gas near the point but not enough to maintain an arc over to the broad electrode. So there is an ionization current in the form of a "brush discharge" near the point. But as the ions traveling away from the point get beyond the surface where the electric field can maintain the arc, the individual ions dissociate and begin traveling through the gas independently.
Similarly, in a field-emission device the concentration of the field near the point leads to a field strong enough to lift electrons off the point.
In both cases the sharper the point, the stronger the field.
Field emission cathodes have been around for decades. Big downside for a vacuum tube (including a flat-panel display) is that the traces of gas in the chamber become ionized and the positive ion (which is massive) is accellerated toward the cathode and tends to strike on or near the point with considerable energy. This ablates the point, degrading and eventually destroying the cathode.
Diamond dust makes very sharp points, which would make it emit well. It is also very hard and conducts heat well, which might make it survive a lot of ion bombardment.
Polycrystaline diamond coatings (which have LOTS of nanoscopic points) can be easily depositied on many surfaces using a device that is essentially a microwave oven filled with low-pressure methane. The microwaves dissociate the methane at the surface, lifting off the hydrogen and leaving elemental carbon behind. The carbon deposits as a mix of diamonds and graphite. Then the microwaves are absorbed by the graphite, vaporizing it and combining it with the hydrogen lifted off it earlier. The diamond stays behind, and gradually grows by absorbing the carbon from other methane molecules.

This post made me think of Dustin Diamond, famous for his roles Screech on Saved by the Bell, Screech on Saved by the Bell: The College Years, and Screech on Saved by the Bell: The New Class. Oh, what a career. OK, now you can get back to what you were discussing, which is a yawn compared to the pal of Zack Morris and A.C. Slater.

Aluminium was once a precious metal (more expensive than gold) (read more at http://www.world-aluminium.org/history/antiquity.h tml ).
And now it is cheap.
Perhaps the diamond (carbon) will be same(cheap) in the future, like aluminium is now cheap.

Um, yeah. Blah blah blah - whatever. Do you really think that I care about the earth eventually stopping its rotation? That'll happen in about a zillion years. What's the point of even saying that?
Cheaper production process just means the manufacturers will be able to increase their bottom line. There is no reason these companies will pass more than a minimal savings on to consumers. Their pricing will be as high as possible but still allow them to generate market share. When their share of the market becomes greater than they can fullfill, their prices will increase. Supply and demand!
But telling people where would only gross them out.
