The influence of dopants on the scintillation properties of PWO crystals was systematically studied, and main attention was focused on the relationship between the crystal components, structure and their properties.

本论文较系统的研究了掺杂离子对PWO晶体闪烁性能的影响，讨论了掺杂晶体组成、结构和性能等方面的关系。

ABSTRACT It occurs that the performance of silicon bipolar transistors degradates seriously at low temperatures due to the gap-narrowing effect、the carrier freeze-out effect and the trapping effect of shallow dopants, which has significant influence on the operation of ultra-high-speed bipolar circuits and BiCMOS circuits at low temperatures.

硅双极晶体管由于禁带变窄效应，载流子冻析效应和浅能级杂质陷阱效应的作用，其电流增益和频率性能在低温下严重退化，从而极大地影响了低温高速双极电路和高性能的低温BiCMOS技术的发展。

It can be easily doped high-quality n-type, but it is difficult to dope p-type. ZnO has largely failed to live up to its potential due to its "asymmetric doping" limitation, such as self-compensation, deep acceptor level, and low solubility of the acceptor dopants.

高质量的n型ZnO很容易实现，但是ZnO的p型掺杂由于其固有的极性却非常困难，这主要是因为ZnO中本征缺陷具有强烈的自补偿，受主元素在ZnO中多为深能级并且固溶度较低。
