Abstract
Polarizability and ground state binding energy values are estimated of an electron bound to a donor confined to move in quantum well wire (QWW) within a variational calculation in the effective mass approximation. The calculations have been performed by using suitable variational wave functions for finite confinement potentials. We present our results for the polarizability as a function of the size of the wire. A comparison with the infinite potential case is presented. The electron-longitudinal optical (LO) phonon interaction is taken into account using the adiabatic approximation. It is found that the polaronic effects decrease significantly the polarizability, increase with increasing wire size and are more pronounced in the case of finite QWW than in infinite QWW.
