Abstract

A novel method previously presented to explicitly solve the Boltzmann equation for highly energetic electrons interacting with polar optical phonons is improved in order to take into account the non-parabolicity of the conduction band. For the case of field free spatial diffusion, the carrier velocity is compared with Monte Carlo simulations. For GaAs the agreement between the analytical and the numerical method is quite good at 77 and 300 K. Also, the results derived for a parabolic band structure show a strong overestimation of the carrier velocity.
