Abstract

The persistent photoconductivity (PPC) of undoped low temperature grown n-AlGaAs has been investigated by temperature-dependent resistance measurements. Five distinct peaks were observed in the resistance measurement results during recovery of the PPC, and the PPC remained up to 260 K. In a sample with a low donor concentration of 1015 cm-3, a new current-dependent PPC also was observed at around 25 K.
