Paper Abstract

The diffusion contribution to thermopower, Sd, is studied for pure semiconducting graphene nanoribbons (GNRs). The electrons are assumed to be scattered by acoustic phonons and optical phonons via deformation potential couplings and edge roughness. Numerical calculations of Sd, as a function of linear carrier density are presented. The relative importance of the carrier scattering mechanisms operative and the effect of subbands on the behaviour of Sd in GNRs are studied.
