  Seeking a better understanding of the electron transport in n-doped zinc
blende GaN and wurtzite AlN, it was performed here a theoretical study
resorting to Non Equilibrium Statistical Operator Method, which provides a set
of coupled nonlinear differential evolution equations that provides a
description of the dissipative phenomena developed in the system. The ultrafast
time evolution (and the steady-state) of the electron drift velocity is
obtained assuming different values for the electron effective mass.
