Monte Carlo investigation of minority electron transport in In 0.53Ga 0.47As

Abstract

The transport of minority electrons in p-type In 0.53Ga 0.47As has been investigated for doping levels of 10 17 and 5×10 17 cm −3. It is found that the electrons exhibit smaller velocities at electric fields below 4 kV/cm when the electron-hole interaction is taken into account. The velocities at fields above 4 kV/cm are higher and reach a maximum at 5 kV/cm. The fraction of electrons that transfer to the upper valleys are significantly reduced for electric fields below 6 kV/cm.
