A theoretical study (by using the Nonequilibrium Statistical Operator Method) is performed on the ultrafast transient transport properties of photoexcited carriers in ZnSe subjected to electric fields up to 35 kV/cm. The electron and hole drift velocity evolution towards the steady state present maxima in subpicosecond scale.
