Title: Charge-Transport Properties of As-Grown Cd 1-xZn xTe 1-ySe y by the Traveling Heater Method

Abstract

In this article, we report on the charge-transport characteristics of a new quaternary material Cd 1-xZn xTe 1-ySe y (CZTS) grown by the Traveling Heater Method (THM). The as-grown CZTS material was found to possess fewer Te inclusions than CZT. Moreover, high resistivity of ~1-2x10 10 ohm-cm was achieved, meeting the requirements of most gamma-ray detector applications. The mobility-lifetime product for electrons [(µτ) e] was measured to be ~4x10 -3 cm 2/V. The energy resolution for the quasi-hemispherical detector fabricated from the as-grown CZTS ingot obtained was ~2.8% (FWHM) at 662 keV.
