More on graphene

"Carbon nanodevices for sensors, actuators, and electronics" at SPIE.

[...]. Despite the promise of vastly superior performance of CNT and graphene-based devices, several fabrication issues need to be resolved to realize their full potential. [...]

Compare to the article which appeared recently in the spanish newspaper "El País" because the main researcher at M.I.T. working on graphene is spanish.

A more scientific explanation of the possible physics experiments done on graphene.

[...] Graphene has long been a theoretical model for 2D crystals. The unique properties of graphene excite theoretical physicists for another reason, too. It turns out that the quantum mechanics of electrons in graphene are identical to the quantum mechanics of massless relativistic particles, with the Fermi velocity (vF, about 10^6 m/sec) taking the place of the speed of light (c, about 3 × 10^8 m/sec). Graphene brings to benchtop equipment experiments that would otherwise require high energy particle accelerators.
