High-field microwave incremental conductivity of cadmium selenide at 77 K

The microwave conductivity of cadmium selenide has been calculated at 77 K assuming a displaced Maxwellian energy distribution function for the electrons. It is found that the microwave conductivity decreases monotonically with the applied electric field and has a lower value for higher impurity concentration. The frequency dependence of the microwave conductivity shows that it is substantially constant up to the millimeter wavelength range of frequencies.
