ELECTRON INTERACTION WITH POLAR OPTICAL PHONONS IN A SEMICONDUCTOR HETEROSTRUCTURE

We investigate the electron-phonon interaction in a Semiconductor Hete rostructure (SH) on the basis of a macroscopic theory for polar optica l phonons (POP) in semicondutor nano-structures. The used theory has l ed to a rather reliable description of POP in quantum wells, quantum w ires and quantum dots. In the present work we derive an analytic expre ssion for the electron-phonon hamiltonian with direct application to a SH. Scattering Rates are calculated by applying this hamiltonian and the obtained results are discussed in detail.
