【摘要】 研究了在厚度为d的薄膜中的激子能级和由于边界极化效应对激子能级的影响;这种影响归结为电子和空穴的镜像电荷对电子与空穴的相互作用.结果发现,这种相互作用对激子的能级有所降低以及对有机薄膜和无机薄膜(它们的介电常数不同)的材料,这种相互作用对激子能级的影响大不相同.更多还原

【Abstract】 The authors discusss exciton energies in a thin film with d thickness and influence of the edge polarization upon the excitons.The polarization is described as interaction between electron(hole) and its image charge.It is found that the interaction decreases the exciton energies to some extent and the influence of the interaction upon the films possessing different dielectric constants and with different thickness are different.更多还原
