摘要
The new experimental systems for investigating the photo-induced phenomena have been constructed. They consist of the photoelectron spectroscopy system based on the synchrotron radiation, the laser system based on the mode-locked pulse lasers, and the experimental system for time-resolved measurements. The systems have been applied to study the surface photo-voltage (SPV) effects on the surfaces of GaAs (100) and GaAs-GaAsP superlattice. The results showed that the temporal profiles of the surface photo-voltage effects have several components in the nano- and micro-second ranges, which depend on the surface conditions.
