[QUOTE][B]The molecular integrated circuit was created by a group of chemists and physicists from the Department of Chemistry Nano-Science Center at the University of Copenhagen and Chinese Academy of Sciences, Beijing. Their discovery has just been published online in the periodical Advanced Materials. The breakthrough was made possible through an innovative use of the two dimensional carbon material graphene.[/B]
[B]First step towards integrated molecular circuit[/B]
Kasper Nørgaard is an associate professor in chemistry at the University of Copenhagen. He believes that the first advantage of the newly developed graphene chip will be to ease the testing of coming molecular electronic components. But he is also confident, that it represents a first step towards proper integrated molecular circuits.
"Graphene has some very interesting properties, which cannot be matched by any other material.
What we have shown for the first time is that it's possible to integrate a functional component on a graphene chip. I honestly feel this is front page news," says Nørgaard.
[B]See through sandwich central to function[/B]
The molecular computer chip is a sandwich built with one layer of gold, one of molecular components and one of the extremely thin carbon material graphene. The molecular transistor in the sandwich is switched on and of using a light impulse so one of the peculiar properties of graphene is highly useful. Even though graphene is made of carbon, it's almost completely translucent.
[B]Environmentally important. Strategically vital[/B]
The hunt for transistors, wires, contacts and other electronic components made from single molecules has had researchers working night and day. Unlike traditional components they are expected to require no heavy metals and rare earth elements. So they should be cheaper as well as less harmful to earth, water and animals. Unfortunately it has been fiendishly difficult to test how well these functional molecules work. Until now.
[B]The luck of the draw[/B]
Previously the testing of the microscopic components had researchers resort to a method best compared to a lottery. In order to check whether or not a newly minted molecule would conduct or break a current, they had to practically dump a beakerfull of molecules between two live wires, hoping that at least one molecule had landed so that it closed the circuit.
[B]Lottery method supplanted by precision placement[/B]
Using the new graphene chip researchers can now place their molecules with great precision. This makes it faster and easier to test the functionality of molecular wires, contacts and diodes so that chemists will know in no time whether they need to get back to their beakers to develop new functional molecules, explains Nørgaard.[/QUOTE]
These science news makes me happy.
I can only imagine this means lower thermals?

And power usage?
I'm very interested in the progress of this tech, hopefully it leads to something. Being able to make computer components out of a graphite base of all things could really provide a staggeringly massive boon to computer manufacturing.
Graphite is cheap and abundant and doesn't damage the environment much, and as such could lead to cheap, powerful and easily disposable/recyclable computer hardware

That sounds completely awesome.
Believe me, I'm very excited to see how technology will be in ten years.
[QUOTE=ichiman94;41130986]These science news makes me happy.[/QUOTE]Yeah, but then years go by and we forget about it.
How is this even possible?
Graphene wins again
Graphene needs to stop being so fucking cool, it's making all the other materials look bad.
What's next, curing cancer? Fucking smug graphene.
and Moore is laughing in his grave

im prity sure they've worked out how to purify saltwater, and destroy smog with graphine, and they are looking at it as a radiation shield too
[QUOTE=Atlascore;41141279]Doesn't graphene cause cancer?[/QUOTE]
I don't think so.
[QUOTE=Atlascore;41141279]Doesn't graphene cause cancer?[/QUOTE]
Everything causes cancer.

Graphene is simply an allotrope of carbon.
So we're fucked if it is because we're made of the stuff.
