Comments on Electrode Self-Energy Effects in Tunnel Junctions

Abstract

Electrode self-energy effects in a tunnel junction have been calculated for a simple model without recourse to the transfer-Hamiltonian formalism. The results are in agreement with earlier suggestions that the electron, in the presence of many-body effects in an electrode, tunnels with the total energy $\ensuremath{\epsilon}$ and not the bare energy ${\ensuremath{\xi}}_{k}=\frac{{\ensuremath{\hbar}}^{2}{k}^{2}}{2{m}^{*}}\ensuremath{-}{\ensuremath{\epsilon}}_{F}$.
