闪锌矿GaN/AlGaN量子点中激子态及光学性质的研究
Exciton states and optical properties in zinc-blende GaN/AlGaN quantum dot
摘要
Abstract
Within the framework of effective-mass approximation, exciton states confined in zinc-blende GaN/AlGaN quantum dot (QD) are investigated by a variational approach, including the three-dimensional confinement of electron and hole in the QD and the finite band offset. Numerical results show that both the exciton binding energy and the interband emission energy decrease when QD height (or radius) increases. Our theoretical results are in agreement with the experimental measurements.关键词
