Abstract
In this article high-frequency cutoff of Fourier spectrum pulse response for drift speed of gallium nitride is investigated. The resulting cutoff frequencies are compared with frequency-domain limits of negative dynamic conductance. The proposed method is based on solution of differential equation system which consists of relaxation expressions for energy, impulse and concentration. Relaxation times used for various kinds of scattering are considered.
