Graphene the soul of a new machine???

Earlier this week the Purdue Computer and Electrical Engineering school had their semi-annual meeting in Dallas. At this presentation Professor Jim Cooper of the Birck NanoTechnology Center talked about Graphene.

Graphene is a single layer of Carbon atoms arranged in a hexagonal configuration -- like chicken wire. Since carbon is in the same column of the periodic table as Silicon it has many of the same characteristics. Professor Cooper described the work they have done to create Field Effect Transistors (FET) out of Graphene.

Although there are some tremendous hurtles to be overcome before this technology can hit the mainstream there are some significant benefits, since some of the issues that limit the future of Moore's law using Silicon can be delayed by a move to a Carbon based approach. One advantage is that many of the same manufacturing techniques currently used can be applied to a Graphene based approach.

There have been a number of stories recently about work being done with Graphene and new possibilities, like a better surface for solar cells... This article describes one approach to making Graphene. Since had great heat transfer and significant electron velocity  advantages we've only seen the tip of the iceberg for where it can be applied.

What are some of your anticipated uses in the hardware layer (data center hosted apps)? Where do you expect the changes to start (cpu, mem,etc).

When should it be expected into commercial use? Seems like I started hearing about the hopes of usage around 2000.

In the presentation the date for any kind of commercial application was a bit out there, 2011-2014.

The breakdown voltage issue for Graphene is not something that anyone has a good handle on. The manufacturing issues are still tough as well. Without addressing these there can be no commercial application. Fortunately, silicon has a few years left in it. ;-)

Here is an article about some high frequency work IBM has done:
