Abstract
With the use of variational solutions to the effective mass equation, we have studied the ground state and the excited state of an impurity bound polaron in quantum well wires (QWWs). Our results show that the binding energies in the ground state and in the excited state increase with increasing confinement of QWWs. The effect of the electron-phono n interaction enhances the binding energies.
