HgCdTe的新型钝化剂 HgCdTe钝化剂的研究是普遍引人注目的课题。业已发现,HgCdTe自然氧化物钝化剂对辐射效应敏感。从传统习惯说来,表面钝化是把二极管性能达到所希望的理论值的一个决定性因素。已证明HgCdTe合适的钝化特别困难,这是因为这种合金的复杂性以及汞蒸汽压所决定的。自然氧化物的化学性质复杂,不适合将p型转变为n~+的过程,因为它能明显地转换成p型材料。而广泛使用的ZnS钝化剂能制备具有优良特性的二极管,但是,它
HgCdTe's new passivating agent HgCdTe passivating agent research is generally the subject of attention. It has been found that HgCdTe native oxide passivators are sensitive to the effects of radiation. From the conventional wisdom, surface passivation is a decisive factor in achieving the desired theoretical performance of a diode. Proper deactivation of HgCdTe has proved particularly difficult due to the complexity of this alloy and the mercury vapor pressure. The chemical nature of natural oxides is complex, not suitable for the p-type into n ~ + process, because it can be significantly converted into p-type material. The widely used ZnS passivator can be prepared with excellent characteristics of the diode, however, it
