Effect of electron-electron interaction on state density in 2D aluminum films
Gershenzon M. E., Gubankov V. N., Falei M. I.
Tunnel spectroscopy has been used to study the effect of the electron-electron interaction on the density of electron states in 2D aluminum films. The experimental data, obtained over broad ranges of the temperature and the magnetic field, can be described quantitatively by the theory of the electron-electron interaction in disordered metals.
