The results show that crystal inhomogeneities and suitable contacts are critical to the fabrication of high quality cdznte spectrometers . the modified growth technique is a new and promising method for growing highly pure and perfect cdznte single crystals . good quality ohmic contact detectors are achieved when gold or indiumare deposited as electrodes on polished and chemically etched surface 结果表明：材料内部的缺陷和欧姆接触是影响器件性能的两个关键因素，采用改进的富镉气氛下坩锅旋转下降法生长的晶体具有较低的缺陷浓度，适合制作探测器，采用au 、 c可得到欧姆接触。
