Nanoscale Thermal Imaging of VO via Poole-Frenkel Conduction
Alyson Spitzig, Adam Pivonka, Alex Frenzel +8
We present a method for nanoscale thermal imaging of insulating thin films using atomic force microscopy (AFM), and we demonstrate its utility on VO. We sweep the applied volta…
Voltage-triggered Ultra-fast Metal-insulator Transition in Vanadium Dioxide Switches
You Zhou, Xiaonan Chen, Changhyun Ko +3
Electrically driven metal-insulator transition in vanadium dioxide (VO2) is of interest in emerging memory devices, neural computation, and high speed electronics. We report on the…
Vanadium dioxide as a natural disordered metamaterial: perfect thermal emission and large broadband negative differential thermal emittance
Mikhail A. Kats, Romain Blanchard, Shuyan Zhang +4
We experimentally demonstrate that a thin (~150 nm) film of vanadium dioxide (VO2) deposited on sapphire has an anomalous thermal emittance profile when heated, which arises due to…
Three-terminal field effect devices utilizing thin film vanadium oxide as the channel layer
Dmitry Ruzmetov, Gokul Gopalakrishnan, Changhyun Ko +2
Electrostatic control of the metal-insulator transition (MIT) in an oxide semiconductor could potentially impact the emerging field of oxide electronics. Vanadium dioxide is of par…
