Features of FeB pair light-induced dissociation and repair in silicon n+-p-p+ structures under ultrasound loading

Abstract

The experimental research in ultrasound impact on iron–boron pair transformation in silicon n+-p-p+ structures has revealed the decrease in concentration of pairs dissociated by light, as well as in the time of pair associations. The FeB pair changes were monitored by measuring short circuit current kinetics. The ultrasound influence was investigated at different light intensities, temperatures, frequencies, and power of acoustic waves. The possible mechanisms underlying the revealed effects were analyzed.
