Abstract
The effects of scattering anisotropy caused by mass anisotropy on the thermoelectric figure of merit and Seebeck coefficient are investigated. The wave-vector-dependent relaxation time is considered to yield transport coefficients. The thermoelectric figure of merit parallel to the conduction layer of a material is shown to decrease as the anisotropy increases. The Seebeck coefficient is shown to be nearly, but not strictly, isotropic
