摘要
在有效质量近似范围内,采用有限深势阱模型,考虑介电受限、计入表面极化效应的情况下,研究了球形、立方形半导体量子点的形状对受限激子的影响.
Abstract Under the effective mass approximation,considering the dielectric confinement effect,we
use the variational method to calculated the binding energy and ground state energy of an exciton
in spherical and cubic quantum dot (QD).The present result shown that the effects of QD shape on
excitonic states in not negligible.
