Highly repeatable nanoscale phase coexistence in vanadium dioxide films
T. J. Huffman, D. J. Lahneman, S. L. Wang +4
The metal-insulator transition (MIT) in vanadium dioxide (VO2) has the potential to lead to a number of disruptive technologies, including ultra-fast data storage, optical switches…
Terahertz nano antenna enabled early transition in VO2
Young-Gyun Jeong, Ji-Soo Kyoung, Jae-Wook Choi +6
We study terahertz transmission through nano-patterned vanadium dioxide thin film. It is found that the patterning allows the lowering of the apparent transition temperature. For t…
Nanoscale imaging of the electronic and structural transitions in vanadium dioxide
M. M. Qazilbash, A. Tripathi, A. A. Schafgans +8
We investigate the electronic and structural changes at the nanoscale in vanadium dioxide (VO2) in the vicinity of its thermally driven phase transition. Both electronic and struct…
Reconfigurable Gradient Index using VO2 Memory Metamaterials
M. D. Goldflam, T. Driscoll, B. Chapler +9
We demonstrate tuning of a metamaterial device that incorporates a form of spatial gradient control. Electrical tuning of the metamaterial is achieved through a vanadium dioxide la…
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…
Infrared spectroscopy and nano-imaging of the insulator-to-metal transition in vanadium dioxide
M. M. Qazilbash, M. Brehm, G. O. Andreev +11
We present a detailed infrared study of the insulator-to-metal transition (IMT) in vanadium dioxide (VO2) thin films. Conventional infrared spectroscopy was employed to investigate…
