Oscillations of energy gap of superconducting vanadium-carbon sandwiches
Tsetlin M.B., Mikheeva M.N.
Tunnel spectroscopy was used to measure the energy gap of superconducting vanadium-carbon sandwiches. It turned out that the gap oscillates in phase with the critical temperature and, furthermore, there are grounds for assuming that the ratio 2A/kTCT behaves in similar fashion.
