摘要：
Ultrasonic treatment of γ-irradiated silicon can lead to a significant (up to about 70%) recovery of the minority carrier lifetime reduced by the irradiation. A mechanism of the ultrasound-induced recovery is proposed, which is based on the release of vacancies from E-type centers followed by their trapping on defect sinks. It is suggested that the role of defect sinks can be played by A-type microdefects.
