Paper Abstract

Cd1-xZnxTe single crystals were grown by Vertical Bridgman method. The optic and dielectric properties of Cd1-xZnxTe (× = 0.04) single crystals in 0.2−2.5 THz frequency range have been investigated by using transmission-type THz timedomain spectroscopy. Two absorption modes at 1.6 THz and at 2.1 THz were observed, which were attributed to the quasi-local mode of ZnTe in CdTe and to the CdTe 2TA phonon process, respectively. The complex refractive index and dielectric function were extracted from the measured transmittance and phase shift in 0.2−2.5 THz range
