Gap of Graphene Ribbon
« on: July 23, 2011, 04:05 »
I took a caculation of a system with two graphene ribbons as a pair of electrodes. The width of the ribbons is N=7, implying that there exists a gap of about 0.5eV. However, the transmission spectra of ATK showed that the conductivity is not zero around zero energy. How can this phenomenon be explained?
Thanks!
