Manipulation of interfacial thermal conductance via Rhodamine 6G

Interfacial thermal conductance plays a sig- nificant role in the heat transfer efficiency of nanoscale systems. The thermal conductance across Al/SiO_2 inter- faces, which is subjected to the change in concentration of sandwiched Rhodamine 6G solution, is measured with time domain transient thermoreflectance technique. The thermal conductance of the interface between Al and SiO_2 logarithmically decreases with an increase in the concen- tration of the Rhodamine 6G solution. This study reveals that heat transport efficiency across an interface can be conveniently manipulated according to the demand of thermal engineering by introducing organic moleculars between both sides of the interface.
