Study on the oxidization characteristics of HgCdTe surface

介绍了一种多路混合信号光纤传输系统。该系统采用单片机完成信号采集、处理和传输，大大简化了硬件电路，缩小了产品体积，提高了系统的可靠性。

Oxidization characteristics of HgCdTe surface are studied by means of X ray photoelectron spectroscopy (XPS).HgCdTe surface exposed in various technological process is measured and analyzed.The results show that the native oxide film on HgCdTe surface closely depends on the process of surface treatment which indicates that the pre treatment prior to HgCdTe surface passivation directly affects the passivation layer HgCdTe interface properties.
