中文摘要	recent infrared spectroscpic observations of local vibrational mode absorptions have revealed a number of photosensitive centers in semi-insulating gaas. they include (ovas) center which has three modes at 730 cm(-1) (a), 715 cm(-1) (b), and 714 cm(-1) (c), respectively, a suggested nh center related to a line at 983 cm(-1) (x(1)), and centers related to hydrogen, such as (h-o) or (h-n) bonds, corresponding to a group of peaks in the region of 2900-3500 cm(-1). the photosensitivity of various local vibration centers was observed to have similar time dependence under near-infrared illumination and was suggested to be due to their charge-state interconversion. mainly described in this work is the effect of the 1.25-ev illumination. it is confirmed that this photoinduced kinetic process results from both electron capture and hole capture, which are closely related to the photoionization behavior and metastability of the el2 center.
