Thermal fluctuations play a significant role in determining the properties of a Josephson junction in certain regimes. The characterization of the effects of fluctuations on a Josephson junction provides useful information relating to the basic problem of the nature of the superconducting normal phase transition. Two experiments have been carried out: one an investigation of the behavior of a Josephson junction when the internal coupling energy is on the order of the thermal energy, the other an investigation of fluctuation induced conductivity in bimetallic Josephson junctions at temperatures between the transition temperatures of the two metal films composing the junction.
