Abstract:We treat a tunneling electron coupled to acoustical phonons through a realistic electron-phonon interaction: deformation potential and piezoelectric coupling, in two-or three-dimensional tunneling configurations. Making use of the slowness of the phonon system compared to electron tunneling, and using a Green function method for imaginary time, we are able to calculate the change in the transition probability due to the coupling to phonons. It is shown using standard renormalization procedure that, contrary to… Show more
