Interface thermal conductance: Factor of 60 range at room temperature W/Al 2 O 3 Au/water PMMA/Al 2 O 3 nanotube/alkane L = Λ/G Λ = 1 W m-1 K-1
Can we beat the amorphous limit of the thermal conductivity Λ min with interfaces? • Einstein (1911): random walk of thermal energy • Not good for crystals: Debye (1914) • but does work for amorphous solids, Birch and Clark (1940); Kittel (1948) • and crystals with strong atomic-scale disorder, Slack (1979); Cahill and Pohl (1988).
