We present a Monte Carlo investigation on the influence of a non-equilibrium phonon population (hot phonons) on second order transport properties in GaAs. We calculate the velocity and energy correlation functions both for the case with and without phonon perturbation. The results show significant modifications in the correlation functions and consequently an increase of the equivalent noise temperature due to the presence of hot phonons.

Abstract
We present a Monte Carlo investigation on the influence of a non-equilibrium phonon population (hot phonons) on second order transport properties in GaAs. We calculate the velocity and energy correlation functions both for the case with and without phonon perturbation. The results show significant modifications in the correlation functions and consequently an increase of the equivalent noise temperature due to the presence of hot phonons.
