Abstract

CdZnTe crystals doped with lead (Pb) in the concentration range of 10 16 - 1019 cm-3 have been grown by the vertical Bridgman method. The structural quality and uniformity of the crystals were verified by chemical determination of etch-pit density and by X-ray rocking curves. Inductively coupled plasma-mass spectroscopy (ICP-MS) was employed for evaluating the dopant concentration and foreign impurities. The electrical properties of CdZnTe crystals were studied by Hall and I-V measurements. These results suggest n-type conductivity and the presence of a compensation mechanism due to the Pb dopant incorporation. It was found that the Pb-doped CdZnTe crystals had resistivity values in the range 109 - 1011 Ω·cm and showed higher dark-current stability.
