Third Harmonic Generation as a Probe of Ultrafast Phase Transitions
… deferential photo detector as well as the first quantitative measurements of the thermal conductance of metal-metal interfaces. The room temperature interface conductance of the as-prepared Al-Cu interface is 4 GW M -2 K-1, and the interface conductance decreases as the interface is made diffuse …
