Abstract
Recently, the thermal energy carried by surface waves along the boundaries of a thin film has drawn much attention. This work reports the measured plasmon thermal conductivity of novel metal films on a glass substrate with a Ti adhesive layer. When considering the size effect of the metal permittivity, a decrease of approximately 30% in plasmon thermal conductivity is observed. The authors demonstrate that the plasmon thermal conductivity of Au and Ag films can reach about 20% of their electron contribution.
