Interesting, have you read of graphene? It's considered almost 2 dimensional as it is a single atom thick sheet of crystalline graphite. It also has many amazing properties relating to electrical use. Electrons move through it at almost 1/10 the speed of light, as they skate across it as opposed to bouncing through a standard wire. Definitely worth looking into as it is like the next step in electronics. Graphene is to digital, as digital is to analogue.
