We report experimental and theoretical work on mesoscopic S–N–S junction in the diffusive regime. The observed temperature dependence of the critical current is compared to results of the quasiclassical theory. Above Ic, the experimental V–I characteristics of the junction deviate strongly from the standard RSJ model. We describe the junction by quasiclassical theory starting from the adiabatic limit. This allows us to extend the RSJ model by introducing a voltage- and phase-dependent resistance as well as an excess current contribution.
