Sharvin resistance
Webb9 dec. 2024 · Analyses show that these observations are due to the more important phonon contribution to the thermal conductance of the point contact as Sharvin resistance greatly hinders electron transport, which is further confirmed by the size dependence of L with a higher value for a smaller contact size. WebbTransports in normal states including the observation of Fabry–Pérot oscillations and Sharvin resistance conclusively witness the ballistic propagation in the junctions. The …

A formula is derived which describes the transition from the Shravin resistance to the Drude resistance when the mean free path becomes comparable to the wire length.
