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…
Electrodynamics of the vanadium oxides VO2 and V2O3
M. M. Qazilbash, A. A. Schafgans, K. S. Burch +5
The optical/infrared properties of films of vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) have been investigated via ellipsometry and near-normal incidence reflectance mea…
Mott transition in VO2 revealed by infrared spectroscopy and nano-imaging
M. M. Qazilbash, M. Brehm, Byung-Gyu Chae +9
Electrons in correlated insulators are prevented from conducting by Coulomb repulsion between them. When an insulator-to-metal transition is induced in a correlated insulator by do…
Hole-driven MIT theory, Mott transition in VO_2, MoBRiK
Hyun-Tak Kim, Bong-Jun Kim, Yong Wook Lee +3
For inhomogeneous high-T_c superconductors, hole-driven metal-insulator transition (MIT) theory explains that the gradual increase of conductivity with increasing hole doping is du…
