Abstract
The instantaneous ensemble-averaged and time-averaged velocity of electrons are presented for Ga0.27In0.73P0.4As0.6, and the results are compared to those for GaAs. The results indicate that both the effective mass in the Γ conduction band and alloy scattering are very critical in determining the transient (or velocity-overshoot) characteristic as well as the static velocity-field characteristic for this quaternary material.
