In this paper, we review measurement techniques for characterizing thermal conductivity and interfacial thermal conductance of solid-state materials in both bulk and thin film forms. 1.THERMAL CONDUCTIVITY OF A METAL ROD AIM OF THE EXPERIMENT: a) To measure the temperature gradient along the length of the metal (copper) rod. E.g., adding impurities introduces scattering centers for conduction band electrons and reduce k.
