ACS Day2: Graphene Ribbons
by mitch on Aug 18 2008 (1962 Views)Dresselhaus of MIT did a review of her many years in carbon nanostructures. She also presented some of her recent work with different types of graphene ribbons. Specifically, for the zigzag case shown below the electronic structure will be highly metallic while the armchair graphene will have a more traditional semiconductor electronic structure.
From graphene to nanotubes to graphene again and now nano ribbons what’s next for the nanostructure field? Gold nanotubes anyone…

Dresselhaus had a very nice paper out in Nano Lett last week on these graphene ribbons. Also, Mullen’s done some very nice work trying to make graphene ribbons from organic precursors. It’s a very fruitful field at the moment, and if graphene really takes off, Novoselov can expect a Nobel in his future.
Thanks for linking to her paper. I did some cursory searches but didn’t turn up anything relevant.
