Abstract
The effects of the electron-phonon interaction on the electron (or hole) en ergy levels in parabolic quantum well (PQW) structures are studied. The gro und state, the first excited state and the transition energy of the electro n (or hole) in the GaAs/Al0.3Ga0.7As parabolic quantum well are calculated by using a modified Lee-Low-Pines Variational method. The numerical results are given and discussed. A comparison between the theoretical and experime ntal results is made.
