Abstract
The method of selective etching was applied to study the influence of electric current pulses with duration 2 × 10−4 s and current density more than 20 MA/m2 on the pyramidal dislocation mobility in Zn monocrystals at 77 and 293 K. It was established that the increase of dislocation mobility under the influence of current pulses is accompanied by multiplication of dislocations at current densitiesj > 102 MA/m2. The obtained results are discussed with the account of electron-dislocation interaction, heating and Frank-Read source operation under the electron wind influence.
