Abstract :
InP MIS structures with applied bias voltage and irradiation of light were studied. It was found that there is an interesting correlation between the density of trap states and the dependence of PL intensities on the bias voltage. PL intensities were found to be affected by the density-distribution of trap states at surface. This behavior of PL intensities was explained by considering only the dependence of the surface-recombination velocity (SRV) on the bias voltage. Analyzing these phenomena makes it possible to estimate surface recombination velocity (SRV) in MIS structures irradiated by light
