Study of scattering mechanisms in p-Ge with magneto-microwave Kerr effect measurements at 24GHz

Temperature variation of the magneto-microwave Kerr effect, in the range 130–430 K, has been studied in two high conductivity samples of p-Ge at a magnetic field of 0.3 Wb m^?2 using a K-band double microwave bridge. The experimental results have been analysed by considering the impurity, acoustic phonon and non-polar optical phonon scatterings. It is found that all the three scatterings play an important role in the present range of temperature. In this temperature range the effective masses of the light and heavy holes are found to be independent of temperature.
