Estimations of the Fermi velocity and effective mass in epitaxial graphene and carbyne
S. Yu. Davydov Ioffe Institute, St. Petersburg
Abstract:
It is shown that the Fermi velocity of electrons is a natural characteristic of gapless graphene and cumulene modification of carbyne weakly coupled with the substrate. At the same time, in the presence of gap (graphene with a gap and polyyne modification of carbyne), the corresponding characteristic is the effective electron mass. The corresponding analytical estimations have been performed.
Keywords:
dispersion relation, density of states, metal and semiconductor substrates.
