量子尺寸效应对InGaN/GaN量子点中的类氢杂质态的影响
Quantum size effect on hydorgenic impurity states in zinc-blende InGaN/GaN quantum dot
摘要
Abstract
Based on the effective-mass approximation, the quantum size effect on binding energy of hydorgenic impurity states in zinc-blende InGaN/GaN quantum dot was investigated by means of variational method. Numerical results showed that the donor binding energy of hydorgenic impurity depended on the impurity position and quantum dot structure in a large extent. The donor binding energy of impurity located at the center of quantum dot was the largest. Impurity donor binding energy decreased when quantum dot height and radius increase for any impurity position.关键词
