摘要

A 60 mm diameter CdZnTe (CZT) ingot with the single-crystal volume over 200 cm³ was successfully grown by using seeded modified vertical Bridgman (MVB) method. To analyze Zn distribution of the as-grown ingot, the near infrared (NIR) spectra of the slice was measured and the cutoff wavelength was calculated. The partition coefficient of Zn during the growth was calculated to be about 1.30. The infrared transmission was flat and high at 2000-4000 cm^-1 with the average value over 60%, while sharply decreased to zero from 2000 cm^-1 to 500 cm^-1. Through I-V curves of the Au/CZT wafers after passivation, the resistivity was calculated to be in the range of 1.8 × 10⁹-2.6 × 1010Ω · cm.
