EFFECTS OF QUANTUM DOT SHAPE ON EXCITONIC STATES
半导体量子点的形状对受限激子的影响

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.
