GaInSb三元合金半导体可用于制作工作于1.55~5.5μm波段范围的光电子器件.在光通讯方面,需要2.55μm波长的激光器和接收器,GaInSb半导体合金无疑是一种可选的材料.此外,这种材料也可用于制作高速电子器件,与GaAs基异质结构相比,Ga...
GaInSb/GaSb quantum wells have been grown by MOCVD technique and the photoluminescence (PL) measurement was performed at 4K. The effects of GaSb capping layer thickness, GaInSb well width and indium content in well on the PL spectra were investigated in detail. It was found that the carrier concentration increased with decreasing the thickness of the capping layer. The FWHM of photoluminescence spectra broaden as the In content in well increased because more clusters should exist in the alloys with high In content and consequently result in the degeneration of the optical quality.
