Abstract

Thermal conductivity measurements on double and triple layers of thin films of silver and a lead-bismuth alloy have been used to determine the energy gap in the silver. In double layers and dirty triple layers the gap is the same as the observed in tunneling measurements. In clean triple layers a smaller gap is observed as a result of the low energy excitations travelling parallel to the interface. An analysis leads to the conclusion that the electron-electron interaction in silver is attractive, with (NV)Ag = 0.1.
