Current oscillations in Vanadium Dioxide: evidence for electrically triggered percolation avalanches
Tom Driscoll, Jack Quinn, Giwan Seo +5
In this work, we experimentally and theoretically explore voltage controlled oscillations occurring in micro-beams of vanadium dioxide. These oscillations are a result of the rever…
Memory Metamaterials
Tom Driscoll, Hyun-Tak Kim, Byung-Gyu Chae +7
The resonant elements that grant metamaterials their unique properties have the fundamental limitation of restricting their useable frequency bandwidth. The development of frequenc…
Synthesis of VO_2 Nanowire and Observation of the Metal-Insulator Transition
Sungyoul Choi, Bong-Jun Kim, Yong-Wook Lee +2
We have fabricated crystalline nanowires of VO_2 using a new synthetic method. A nanowire synthesized at 650^oC shows the semiconducting behavior and a nanowire at 670^oC exhibits…
Mott transition observed by micro-Raman scattering in VO_2
Hyun-Tak Kim, Byung-Gyu Chae, Bong-Jun Kim +3
A strongly correlated Mott first-order metal-insulator transition (MIT) (or Jump) not accompanied by the structural phase transition (SPT) was clearly revealed in VO_2, (New J. Phy…
Highly oriented VO2 thin films prepared by sol-gel deposition method
Byung-Gyu Chae, Hyun-Tak Kim, Sun-Jin Yun +4
Highly oriented VO2 thin films were grown on sapphire substrates by the sol-gel method that includes a low pressure annealing in an oxygen atmosphere. This reduction process effect…
