摘　　要：导电类型转换(CTC)描述了掺杂或非故意掺杂碲镉汞(MCT)材料导电特性的p-to-n或n-to-p的改变过程。对CTC机制的深入理解涉及物理、电学和化学等多种学科。迄今为止的相关进展主要是经验性的。主要通过对近年来部分英文文献进行归纳分析,以离子束研磨工艺为重点,介绍了MCT/CTC的研究进展。Conductivity type conversion （CTC） describes the process resulting in a p-to-n or n-to-p conductivity change in doped or unintentionally doped mercury cadmium telluride （MCT） materials. The thorough understanding of CTC mechanisms involves the knowledge of diverse fields of electrical science, physics, chemistry and etc.. The related progress to date has been primarily empirical. By summarizing and analyzing some related papers published in recent years, this review describes the MCT/CTC research progress of MCT/CTC with emphasis on ion beam milling techniques.
