The effect of tunnel currents in superconducting junctions on the energy gap is calculated. For certain parameters two different gaps can exist. The stability of these solutions is investigated and at a certain voltage a first order transition is found. This result explains the experimentally observed inhomogeneous states in superconducting tunnel junctions. Author
