Spotlight Podcast Episode 32: Krishen Appavoo – phase change material, vanadium dioxide. Typically an insulator, when given a small amount of energy, it becomes conducting and has applications in next generation electronic devices
Dec. 31, 2020—In Episode 32 of the VINSE Spotlight Podcast Kannatassen ‘Krishen’ Appavoo tells Alice Leach about the phase change material, vanadium dioxide. Typically an insulator, when given a small amount of energy, it becomes conducting and has applications in next generation electronic devices. Krishen’s paper “Doping-driven electronic and lattice dynamics in the phase-change material vanadium dioxide”...
