Abstract

Abstract The Fröhlich Hamiltonian describing the interaction of longitudinal-optical (LO) phonons and charge carriers in a quantum wire have been derived previously by imposing boundary conditions on the electrostatic potential of the phonon field. In this study, the Fröhlich Hamiltonian for a quantum wire is derived by taking into account appropriate mechanical boundary conditions and the resulting Hamiltonian is used to calculate the total scattering rate for electron-LO-phonon scattering.
