To: @corradini. You are absolutely right the band-gap is a distance from the top of the valence band to the bottom of the conduction band...this research shows that presence of moisture modifies crystalline structure and changes the band-gap...whether that effect can be exploited practically is another story...Kris
Ummm....I'm not an EE, or physicist, or anything remotely similar and thus qualified to hit the "oops" buzzer, here (I just think stuff up and try to make it ;-) BUT: isn't bandgap actually the 'distance' (in eV) from the TOP of the valence band to the BOTTOM of the conduction band?
indeed an exciting article and with 2010 nobel prize to graphene, this is surely an exciting time for the researchers working in this area. i wonder what are the main challenges and difficulties to open a wider bandgap in graphene?
Now I see how that is supposed to be used in computers. I heard that once this technology is mature, it'll make computers faster than ever. I wonder if that "a million time better" sentence in the first paragraph comes out from a hard number or just an expression.
If conductivity is the only benefit of graphene inside chips that would mean that the IC's would become much more energy efficient... thus... lower heat dissipation, and such can reflect in the processing power of the chips.
Did you hear that the 2010 Physics Nobel Prize wan the 2004 Ig Nobel too?... Goggle it.
