摘要

Optical absorption of quantum dots is investigated using the adiabatic approach, in which a Fröhlich-type interaction between electron-hole pair and longitudinal optical phonons has been assumed. The role of the finite barrier potentials in predicting the magnitude of the Huang-Rhys factors is considered. For the small GaAs/AlAs quantum dots, the Huang-Rhys factors are found to be larger than those in the bulk phase by one to two orders of magnitude. The absorption and photoluminescence spectra of such nanostructures are analyzed.
