Abstract:
Thermoelectric effect in graphene monolayer is hereby analyzed in the wide temperature range of 10–300 K, based on semiclassical Boltzmann equation and theory of linear response. The solutions of Boltzmann equation are found in the approximation of relaxation time for different relaxation mechanisms of charge carriers, with temperature dependence of the corresponding relaxation times adopted from the literature. Temperature dependence of graphene thermoelectric power is numerically found and compared with the experimentally observed data. The dependance of graphene thermoelectric power on the concentration of charge carriers is analyzed as well.

Key words:
thermoelectric power, relaxation time, Boltzmann equation
