Negative differential mobility in GaAs at ultrahigh fields: Comparison between an experiment and simulations
Direct measurement of the electron velocity v(n) at an extreme electric field E is problematic due to impact ionization. The dependence v(n)(E) obtained by a Monte Carlo method can be verified, however, by comparing simulated and experimental data on superfast switching in a GaAs bipolar transistor...
