And some success in carbon nanotubes too.

All transistors are analog. Some are just USED in off and saturation mode.

I think they were referring to the application type rather than transistor type.

Another potential great application of graphene:

‘In most materials, one absorbed photon generates one electron, but in the case of graphene, we have seen that one absorbed photon is able to produce many excited electrons, and therefore generate larger electrical signals’ said Frank Koppens, group leader at ICFO.

Some more very cool carbon stuff can be found here,

New nanotube fibers have unmatched combination of strength, conductivity, flexibility (w/ video)

Graphite = a variety of carbon crystal structure (the other one is diamond). Graphite oxide = CO2 You are safe to put it in a DVD burner Some even go as far as put it in water and sell it as soda

Graphene transistors display self-cooling ability | Science Technology

IBM hits 155 GHz with 40nm graphene transistor | Science Technology

Thought about the spaceships described in Alastair Reynolds books when I first read about the self cooling ability.
