The excess current in superconducting point junctions
Artemenko S.N., Volkov A.F., Zaitsev A.V.
It is shown theoretically that at high voltages V > > Δ/e the current in the junctions is the sum of the ohmic current V/R and of the excess current 7exc. The obtained value /ехс = (7г2/4 — \)A/2eR agrees with the experimental data.
