半导体中杂质和点缺陷的电子结构

Electronic structures of impurities and point defects in semiconductors

Yong Zhang

摘要:

简要介绍了半导体中杂质理论的发展历史。本文提出了一个适用于类施主、类受主杂质和点缺陷的束缚激子模型,它对“浅”、“深”杂质和点缺陷提供了统一的认识。使用不同的密度泛函理论为基础的方法的计算结果的基础物理进行了讨论和解释的束缚激子模型的框架。

英文摘要:

A brief history of the impurity theories in semiconductors is provided. A bound exciton model is proposed for both donor- and acceptor- like impurities and point defects, which offers a unified understanding for "shallow" and "deep" impurities and point defects. The underlying physics of computational results using different density-functional theory based approaches are discussed and interpreted in the framework of the bound exciton model.
