英文摘要	In this paper, the detection wavelength and the electron-hole wave function overlap of inas/irxga1-xsb type ii superlattice photodetectors are numerically calculated by using the envelope function and the transfer matrix methods. the band offset is dealt with by employing the model solid theory, which already takes into account the lattice mismatch between inas and inxga1-xsb layers. firstly, the detection wavelength and the wave function overlap are investigated in dependence on the inas and inxga1-xsb layer thicknesses, the in mole fraction, and the periodic number. the results indicate that the detection wavelength increases with increasing in mole fraction, inas and inxga1-xsb layer thicknesses, respectively. when increasing the periodic number, the detection wavelength first increases distinctly for small periodic numbers then increases very slightly for large period numbers. secondly, the wave function overlap diminishes with increasing inas and inxga1-xsb layer thicknesses, while it enhances with increasing in mole fraction. the dependence of the wave function overlap on the periodic number shows the same trend as that of the detection wavelength on the periodic number. moreover, for a constant detection wavelength, the wave function overlap becomes greater when the thickness ratio of the inas over inxga1-xsb is larger.
