Abstract
The transport of minority electrons in p‐type In0.53Ga0.47As has been investigated for 1017 and 5×1017 cm−3 doping levels. Using Monte Carlo methods and including inelastic electron‐hole (e‐h) scattering, it is found that the mean electron velocity for fields below 4 kV/cm is smaller when e‐h scattering is included than when it is absent. The mean velocities above 4 kV/cm are higher when e‐h scattering is included and reach a peak at 5 kV/cm. The study reveals that the principal contribution of the e‐h scattering is a more efficient channel of electron energy relaxation, with the consequence of a significantly reduced transfer of carriers to the upper valleys for fields below 6 kV/cm.Keywords
