Researchers Create Glass Just 3 Atoms Thick
sciencehabit writes "Researchers have created the world's thinnest pane of glass. The glass, made of silicon and oxygen, formed accidentally when the scientists were making graphene, an atom-thick sheet of carbon, on copper-covered quartz. They believe an air leak caused the copper to react with the quartz, which is also made of silicon and oxygen, producing a glass layer with the graphene. The glass is a mere three atoms thick — the minimum thickness of silica glass—which makes it two-dimensional. The team notes that the structure 'strikingly resembles' a diagram drawn by a glass theorist attempting to unravel its structure back in 1932. Such ultra-thin glass could be used in semiconductor or graphene transistors." See Nano Letters for an abstract (and another picture) to the paywalled article.
And in related news, iPad 4 rumored to be just 2mm thick.
The glass is a mere three atoms thick — the minimum thickness of silica glass—which makes it two-dimensional.
It's not two dimensional if it has a measurable thickness, which you stated in that same sentence. Unless you have a different definition of "two dimensional" than the rest of us.

More glass cellphones with easy to break screens and backs!
Do not look at laser with remaining good eye.
it can also create very thin glass! Go graphene!
...but I think an old landlord of mine managed to do this, many years ago.

How long before they broke it?
http://en.wikipedia.org/wiki/Quartz "It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2."

Now I'll have to keep kids from breathing on my windows, much less throwing a baseball through them!
Those people in atomic glass houses really shouldn't throw anything!
You must have never dropped an iPhone 4/S from a foot up on something that isn't memory foam.
I'll be spending my money on the iPad5S, four atoms and a suspended quark thick! Have fun wasting your money!
While you post comments, do you read the summary at all? Or do you just read the first few letters and decide to post your thoughts?
"Such ultra-thin glass could be used in semiconductor or graphene transistors."
I'm sure we'll invent something for this invention.

I'm thinking it could be used as an insulator sandwiched inside of something. Don't know of any actual uses like that, but I'm sure someone else can come up with one.
Honesty may be the best policy, but by process of elimination, dishonesty is the second best policy.
It is said the most amazing discoveries come from a scientist saying "gee that's funny..."
By accidentally producing this very cool new material they have according to the abstract made the first electron microscopy of glass, allowed by this very thin layer being supported by but not bonded to the underlying graphite. And from the amazing picture they took, which amazingly resembles drawings made by a glass theorist 80 years ago, they were able to make calculations showing that the weak van der waals force is what's keeping this thing stable.
It is a totally awesome thing they found and probably gives them whole new ideas about how to grow thin 2d structures. Just a week ago there was another bit of news about awesome 2d ice channels in graphite that open and close to keep helium from going through them. Sounds like there are tons of totally awesome things that are possible in these crenulated 2d realms and graphite is helping us discover them.
Perhaps someone else here can theorize about what it all means.
Glass and quartz.
Glass that consists of nothing other than silicon and oxygen-- chemically known as "silica"-- is referred to as "quartz".
When they say they grew the material in "quartz" tubes, they mean: tubes made of silica glass. (Mineralogists reserve the word for only crystalline silica, but when they say a quartz tube, it's quartz glass, i.e. silica, not the mineral.) When they say that the substrate was "copper-covered quartz" they mean: "copper-covered silica glass". When they say they made glass consisting of two atoms of oxygen and one atom of silicon, they mean: silica glass.
So: they're saying that silica glass is silicon and oxygen, and, also, so is silica glass.

Quartz has a regular crystal structure, glass doesn't.
If I draw a picture on a piece of paper, we call that drawing two-dimensional despite the fact that the graphite and pulp that is formed with have thickness. Likewise, if a crystal only grows along a plane (rather than in three dimensions), then that crystalline structure is two-dimensional, even though the crystal itself is a three dimensional object. This is the same thing, the sheet of glass is three-dimensional, but the structure of the amorphous solid is two-dimensional.
This was already said and responded to. Apparently the material is (obviously) not mathematically two dimensional, but there's also a physical concept of 2D which involves a material having reached its absolute minimum thinness. The molecules in glass are three atoms thick, therefore the thinnest possible glass is three atoms thick. According to the physical definition of 2D, this material is.
I don't need a million points of light, just two points of multi-mode fiber and a 10 Gig-E router.
Might this be a good for improving MOS transistors (gate/channel insulator)?
A keyboard! How quaint.
"Quartz has a regular crystal structure, glass doesn't."
If you're a mineralogist. Try looking up "quartz glass" or "fused quartz" in google.

Not having access to the full article I can't tell, but there is a big difference between coating a copper layer (on silica) with another layer of very thin silica and a pane of glass, which I would think is a stand alone structure. Anyone know? Still quite neat.
Sounds like the glass is half full to me.

In an earlier version of the script, the crew travel back in time to rescue the sperm whale, rather than the humpback whale, but due to an unfortunate communications error they end up trying to make a very small glass tank...

I'm thinking that the leakage through such a thin layer of oxide would make it useless as an insulator in transistors.
...the future crusty old bastards are already drinking the Kool-Aid.

Maybe one could do a tunneling junction.
Practical applications for new materials and other discoveries are seldom apparent at first. Even new inventions. Fifteen years ago everyone was asking me "why on earth do you have a computer?" When Edison invented voice recording, there were no practical applications for that, either, until Bell turned the wax cylinder into a shellack disk and people started listening to records.
And what's wrong for discovery for the sake of discovery? I'll bet you think astronomy is a wasted science and never should be funded, too.
It boggles the mind that a comment like that would show up on slashdot, of all places. WTF???

Aluminum Oxide, AKA Sapphire, is transparent aluminum.
If the object itself is three dimensional, it's a physical impossibility for the structure to also be two dimensional. A two dimensional structure has NO THICKNESS WHATSOEVER. What you're describing is the mollecular bond of the crystalline structure running along the same plane. That's not a two dimensional object, there, buddy, that's a FLAT SURFACE. Big difference. Am I going senila or are the basic laws that govern our universe really that difficult to grasp? Fuck, if this is our future...
Well, excuse me for hitting the "end" button when I loaded the page. In the meantime, why don't you read something relevant to the laws of the universe AND the discussion instead of arguing with fallacy and half-baked theoretical conjecture. Incidentally, physical concepts are ENTIRELY mathematical, in case you haven't been paying attention in class.

This reminds me a bit of a transistor...
Perhaps all these ways we're figuring out to manipulate things on an atomic scale will have some payoff in computing. It could be as simple as smaller fab processes for conventional computer chips. It could be evolutionary advancements of current chip technology, that's somehow augmented by using this new atom-level manipulation. Or it could mean revolutionary advancements, like quantum computing or some as-of-yet unimagined computing paradigm.
I was hoping for a monofilament wire :(
