New Charge-Storage Effect in SiliconpinDiodes at Cryogenic Temperatures

Abstract
A peak was observed in the IV characteristic of silicon pin diodes at liquid-helium temperatures when the voltage was changed rapidly in the reverse-bias direction. The size and structure of the peak were dependent upon the integrated incident light, or forward injection. The intrinsic rise time of the peak was found to be less than 0.3 nsec.
