Abstract

The influence of the heterointerface on the energy spectrum of shallow and deep centers is considered. Formulas are obtained for broadening of the impurity-center energy and the electron lifetime in the quasistationary state. The corresponding analytical formulas obtained in other works are refined. It is shown that in this case the effective radius of a shallow center is not its Bohr radius r_B, but 2.5r_B.

异质界面附近的供体能级和宽度

摘要

考虑了异质界面对浅中心和深中心能谱的影响。获得了用于扩大准稳态下的杂质中心能量和电子寿命的公式。完善了在其他著作中获得的相应分析公式。结果表明，在这种情况下，浅中心的有效半径不是其玻尔半径ř_乙，但2.5 - [R_乙。
