主 题:InGaN photoluminescence full width at half maximum
摘 要:In our experiments,the PL spectra of several In x Ga 1 x N alloy samples with In contents x=0.1,0.15 and 0.25 were measured as a function of temperature ranging from 10 K to 300 K.S-shaped temperature dependencies were observed in all InGaN samples and a sharp decrease in the full width at half maximum occurred with decreasing temperature in the moderate temperature *** was found that both phenomena are relative to localization *** addition,the degree of localization effects in three samples was investigated using the band-tail *** findings are presented in this paper.
