Vanadium Dioxide SEM (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption 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 Usage Restrictions Editorial use only.
