Non-equilibrium Coulomb effects significantly modify tunneling processes.
Theoretical framework explains experimental tunneling anomalies.
Abstract
Non-equilibrium Coulomb effects in resonant tunnelling processes through deep impurity states are analyzed. It is shown that Coulomb vertex corrections to the tunnelling transfer amplitude lead to a power-law singularity in current- voltage characteristics
