Abstract
We present Monte Carlo calculation results and qualitative discussion indicating that the velocity versus electric field surve in compensated gallium arsenide at cryogenic temperatures should have two maxima. One of the consequences of this new M-shaped velocity-field dependence should be a drastic decrease in the maximum electric field in the high-field Gunn domain accompanied by a change in the domain shape from triangular to trapezoidal.Keywords
