Abstract

The diffusion contribution to thermopower, S_d, 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 S_d, 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 S_d in GNRs are studied.
