Paper Abstract

The Hamiltonian describing the iteraction of both confined longitudinal-optical and surface-optical photons with charge carriers is derived from the macroscopic dielectric continuum model for the case of a rectangular quantum wire where photon confinement occurs in two of the three spatial dimensions. The full interaction Hamiltonian is used to calculate the total scattering rate for electron-optical-phonon scattering of electrons traversing a GaAs square quantum wire. The results demonstrate that the interaction by the surface-optical phonon modes is very strong and may dominate over other scattering processes, especially with dimensions of about 100 A or less. A considerable decrease in the total scattering rate for optical phonons as a result of simple reduction in dimensionality is not observed in this study.
