Abstract

Far-infrared (FIR) reflectance spectroscopy was employed to study a series of bulk Cd_1-xZn_xTe with varying Zn content (0-100%) and bulk CdSe_xTe_1-x with varying Se content (5-35%). The dielectric response function model and least-square fit were used to find the optical and transport parameters. With an increase in the Zn content, the effective mass of Cd_1-xZn_xTe increases slightly, while the carrier concentration increases significantly; however, the mobility and conductivity decrease. With an increase in the Se content, the effective mass of CdSe_xTe_1-x decreases slightly, while the mobility, carrier concentration, and conductivity increase significantly.
