  We present a detailed ab-initio study of semi-classical transport in n-ZnSe
using Rode's iterative method. Inclusion of ionized impurity, piezoelectric,
acoustic deformation and polar optical phonon scattering and their relative
importance at low and room temperature for various n-ZnSe samples are discussed
in depth. We have clearly noted that inelastic polar optical phonon scattering
is the most dominant scattering mechanism over most of the temperature region.
Our results are in good agreement with the experimental data for the mobility
and conductivity obtained at different doping concentrations over a wider range
of temperatures. Also we compare these results with the ones obtained with
relaxation time approximation (RTA) which clearly demonstrate the superiority
of the iterative method over RTA.
