Effect of electron-electron interaction on tunneling conductivity of bismuth films
Lutskii V. N., Rylik A. S., Savchenko A. K.
The conductivity G of a tunnel structure Bi film-Bi oxide-Pb film exhibits a symmetric minimum when there is no voltage (V) across the junction. The zero anomaly of G(V) and its temperature dependence are interpreted in terms of the theory of electron-electron interaction in disordered systems.
