While researching graphene electronics, I found an excellent resource courtesy of the Kavli Institute for Theoretical Physics at UC Santa Barbara. They held a two week seminar on the subject last year, and put all of the talks online. Not just the slides, but audio and video of all the presentations. Definitely worth a look.
(Highly technical: physicists talking to other physicists. As this is a fast-moving field, these talks may not represent the current state of the art.)
The research was for a feature for Solid State Technology magazine, hopefully the May issue.
