Visualizing temperature transport: An unexpected technique for nanoscale characterization

As devices continue to shrink, new challenges in their measurement and design present themselves. For devices based on molecular junctions, in which single molecules are bound to metals or semiconductors, we have a variety of techniques to study and characterize their electric transport properties. In contrast, probing the thermal transport properties of such junctions at the nanoscale has proven more challenging, and many temperature-related quantum phenomena in them remain poorly understood.
