Measurement of the velocity-field characteristic of indium phosphide by the microwave absorption technique

The electron velocity-field characteristic has been determined for a large number of samples of InP by the microwave absorption technique. The values obtained for the electric field at the peak of the velocity-field curve are corrected for relaxation effects by comparison with a computer simulation, and the resulting values lie in the range 7.2-9.8 kV/cm^-1. The corrected negative dynamic mobility just beyond the peak velocity varied between 0.3 and 0.5 of the low-field mobility.
