摘要

Electrical and optical properties of HgCdTe are crucial for detectors. Infrared photoluminescence (PL) spectra in the temperature range of 11-300K and Hall data were recorded on the arsenic-doped narrow-gap HgCdTe epilayers. Curve fittings of PL spectra indicate that As_Te, V_Hg, Te_Hg-V_Hg and Te_Hg exist in the arsenic-doped HgCdTe epilayers after the two-step annealing. More Te_Hg-V_Hg pairs are created when the dopant concentration is increased. Analysis of temperature-dependent Hall data verifies the existence of Te_Hg, which lowers the mobility of the material.
