Vanadium dioxide (VO2) nanobeams synthesized by Berkeley researchers show exotic electrical and thermal properties. In this false-color scanning electron microscopy image, thermal conductivity was measured by transporting heat from the suspended heat source pad (red) to the sensing pad (blue). The pads are bridged by a VO2 nanobeam. Credit: Junqiao Wu/Berkeley Lab

The findings of vanadium dioxide properties could lead to a wide range of applications, such as thermoelectric systems that convert waste heat from engines and appliances into electricity, window coatings. For most metals, the relationship between electrical and thermal conductivity is governed by the Wiedemann-Franz Law. Simply put, the law states that good conductors of electricity are also good conductors of heat...
