摘要：
We carried out the theoretical study of the influence of temperature on the polaron vibration frequency in the RbCl asymmetrical semi-exponential quantum wells by using the quantum statistical theory. The vibration frequency and the ground-state binding energy (GSBE) varying with the temperature and the Coulomb interaction are calculated by employing the Lee-Low-Pines transformation method combined with linear combination operation technique. We show that the vibration frequency and the GSBE will be enhanced with raising the temperature and the Coulomb repulsion interaction.
