Solid-solid junctions with an interfacial self-assembled monolayer (SAM) are a class of interfaces with very low thermal conductance. Au-SAM-GaAs junctions were made using alkanedithiol SAMs and fabricated by nanotransfer printing. Measurements of thermal conductance using the 3ω technique were very robust and no thermal conductance dependence on alkane chain length was observed. The thermal conductances using octanedithiol, nonanedithiol, and decanedithiol SAMs at room temperature are 27.6±2.9, 28.2±1.8, and 25.6±2.4 MW m-2 K-1, respectively.
