ELECTRON-MOBILITY IN THE IMPACT IONIZATION REGIME OF INSB

Recent laser-induced impact ionization experiments with InSb are evalu ated using the similarity principle for the same process in the presen ce of de fields. It is shown that the deduced electron mobility is wel l-described by the Das-Ferry model considering only inelastic collisio ns with LO phonons in the Gamma-valley conduction band. The calculatio n uses established physical constants and no fitting parameters.
