Abstract
We have calculated the longitudinal optical phonon scattering contribution to electron tunneling through a double-barrier diode. Our model takes into account the delocalization of the incident electron over the whole structure as well as the momentum transfer between electrons and phonons. Our results, obtained without fitting parameters, give considerably improved estimates of the experimentally observed valley current and its dependence on temperature.Keywords
