Abstract
The polaron ground state energy and the mean number of LO phonons are obtained by using variational method of Pekar type on the condition of strong electron-LO phonon coupling in a RbCl quantum pseudodot under applied electric field. The dependences of the polaron ground state energy and the mean number of LO phonons on the temperature and the electric field are derived by employing quantum statistical theory. It is found that the absolute value of the ground state energy increases when the temperature is increased at lower temperature regimes, and decreases when the temperature increases at higher temperature regimes. The mean number of LO phonons aggrandizes with increasing temperature. The absolute value of the ground state energy is a raising function of the electric field, whereas the mean number of LO phonons is a decaying one of it.
