摘 要: | The influence of the electron-LO-phonon coupling on energy spectrum of the low -lying states of an exciton in parabolic quantum dots is investigated as a function of dot size.Calculations are made by using the method of few-body physics within the effective-mass approximation.A considerable decrease of the energy in the stronger confinement range is found for the low-lying states of an exction in quantum dots.Which results from the confinement of electron-phonon coupling.
