Effect of transverse magnetic field on the electromagnetic wave propagation in semiconductor plasmas at high electric field

Abstract

Instabilities of electromagnetic (e. m. ) waves in semiconductor plasmas in the presence of a transverse magnetostatic field have been studied by a number of workers under different assumptions /1 to 7/. None of the earlier workers has studied the growth rate and its nature of variation with the system parameters. istics of the unstable mode in both n-type and two-component semiconductor plasmas taking into account the hot carrier effect, the Hall drift, and the appropriate scattering mechanisms. 2 2 3 c j J and a. = w -( G jiv.) .Equation (2) under an appropriate coordinate system reduces to equation (1 7) of Gueret /6/ if the inertial term is neglected (viz., 6 . << v . ) .
