A method is proposed for determining the electron - hole scattering parameters in indirect gap semiconductors when the carrier injection level is low. The proposed method is used to study the electron - hole scattering in silicon. The results are evidence that minority carrier complete drag by majority-electrons is possible in n-type material at a doping level of Nd > 1017cm-3 even at room temperatures.
