Scientists Build Three Atom Thick LEDs
minty3 tipped us to news that UW researchers have built the thinnest LEDs yet: a mere three atoms thick. Quoting El Reg: "Team leader Xiaodong Xu, a UW assistant professor in physics and materials science and engineering, and his graduate student Ross, have published the technique in the latest issue of Nature Nanotechnology. They report that the LEDs are small and powerful enough to be used in optical chips that use light instead of electricity to shuttle signals and data through a processor, or they could be stacked to make new thin and flexible displays."
When I see it!
Unfortunately, that means they have to be several kilometers in width...
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
Did all the work, gets zero return.
And how many atoms thick does the insulating layer between adjacent photosensitive or photoemitting structures need to be to prevent light emitted by one pair's LED from unduly influencing the state of an adjacent photodiode/phototransistor?
What, exactly, is the benefit of building a chip whose internal connections are basically all optoisolators?
I'm impressed that they didn't just build one one atom thick LED, but three of them. Was it to prove they could reproduce it?
I think the iPhone 6 or 7 is going to be the thinest iPhone yet... and at 3 atoms thick, sharper than the sharpest knife. Careful pulling that out of your pocket, you might loose all your fingers if you're holding it wrong. :P
To be clear, only two authors are from the University of Washington. They have many collaborators, including from Univ. of Tennessee, Oak Ridge NL, Germany, Japan, and Hong Kong.
Submitter: University of Wisconsin and University of Waterloo are also known as "UW". It's worth expanding on first use.
boldly going forward, 'cause we can't find reverse
So the electrons from how many atoms cross the junction?
It was published in Nature Nanotechnology.
Isn't it really Angstromtechnology?
Besides, I though that nanotechnology applied to complicated 3D structures of nanotubes and such. If it's flat and produced by epitaxial growth, is it really sexy enough to be called Nanotechnology?
Just put ?nobeta=1 to the end of the URL.

Why didn't they just build one ?

Not to mention U of WTF
Does anyone else remember when IBM would be the one to do something like this?

Things are getting thinner and thinner. Technology It is! and This can be a lot more spacious.

There are two other publications in the same issue of Nature Nanotech., both of which also report the creation of similar systems also utilizing monolayers of WSe2: this one from a group at the Vienna University of Technology and this one from a group at MIT.
We can observe clear evidence that Moore’s Law is ending, because we can point to a pattern that precedes the end of exploiting any kind of resource. But there’s no reason to panic, because Moore’s Law limits only one kind of scaling, and we have already started another kind.
...an article with little enough grasp on basic scientific principles to include this gem: "The new LEDs measure just three atoms tall, technically making them 2D rather than 3D objects"
Um, no. No it doesn't. See that word "tall"? That's how you know.
Audi announced new tail lights that are just 3 atoms thick.
slashdot = stagnated
That's why AC doesn't get mod points.
Hmm, 3 atoms for the LED and a million atoms for each solder joint.
Is it a single LED that is three atoms thick, or are there 3 individual atom thick LEDs?
If the latter, 1 atom thick is just an atom. So these guys are claiming to have invented an atom.
