We have calculated the ionization energy of a bound polaron confined in general step quantum wells (QWs) in the presence of an electric field, in which the coupling of an electron with confined bulk-like LO phonons, half-space LO phonons and interface phonons is considered. In particular, the intera

By using a modified Lee-Low-Pines variational method, we have investigated the groundstate binding energy of a polaron confined in asymmetric single and step quantum wells (QWs) due to interface phonons, confined bulk-like LO phonons, and half-space LO phonons. The relative importance of the differe
The ground-state energy of bound polaron in quantum confinement has been calculated by using N-variational parameters to Feynmans approximation action. The method of calculation is based on the Jensen-Feynman inequality which provides an upper bound for the ground-state energy of the polaron in quan
The ground-state energy of bound polaron was obtained with strong electron-LO-phonon coupling using a variational method of the Pekar type in a parabolic quantum dot (QD). Quantum transition occurred in the quantum system due to the electron-phonon interaction and the influence of temperature. That
