Temperature Dependence on State Energies and Transition Frequency of Polaron in a Quantum Well with Asymmetric Gaussian Potential: Strong Coupling Method

In the present work, the influence of temperature effect on polaron in a quantum well (QW) with asymmetric Gaussian potential (AGP). By employing strongly coupling method of Pekar variational (SCMPV), the ground state (GS), the first-excited state (FES) energies and transition frequency (TF) of the polaron are derived. The state-energies and the TF as relationship of the temperature T and the electron phonon coupling strength (EPCS) are obtained by using quantum statistics theory (QST). We have found that the state-energies and the TF increase when the temperature is increasing. The states-energies and the TF are decreased with raising the EPCS.
