Thermal Boundary Resistance

Caption

Rice University scientists trying to measure the plasmonic properties of a gold nanowire (right) found the wire heated up a bit when illuminated by a laser at room temperature, but its temperature rose far more when illuminated in ultracold conditions. The effect called thermal boundary resistance (Rbd) blocks heat deposited in the gold (Q) from being dissipated by the substrate.
