Journal ArticleDOI
Mott Transition in VO2 Revealed by Infrared Spectroscopy and Nano-Imaging
M. Mumtaz Qazilbash,M. Brehm,Byung-Gyu Chae,Pei-Chun Ho,Gregory O. Andreev,Bong-Jun Kim,Sun Jin Yun,Alexander V. Balatsky,M. B. Maple,Fritz Keilmann,Hyun-Tak Kim,Dimitri Basov +11 more
TL;DR: The electronic properties of a prototypical correlated insulator vanadium dioxide in which the metallic state can be induced by increasing temperature is reported, setting the stage for investigations of charge dynamics on the nanoscale in other inhomogeneous correlated electron systems.
Journal ArticleDOI
Ultra-thin perfect absorber employing a tunable phase change material
Mikhail A. Kats,Deepika Sharma,Jiao Lin,Patrice Genevet,Romain Blanchard,Zheng Yang,M. Mumtaz Qazilbash,Dimitri Basov,Shriram Ramanathan,Federico Capasso +9 more
TL;DR: In this paper, the authors show that perfect absorption can be achieved in a system comprising a single lossy dielectric layer of thickness much smaller than the incident wavelength on an opaque substrate by utilizing the nontrivial phase shifts at interfaces between lossy media.
Journal ArticleDOI
Dynamic tuning of an infrared hybrid-metamaterial resonance using vanadium dioxide
Tom Driscoll,Sabarni Palit,M. Mumtaz Qazilbash,M. Brehm,Fritz Keilmann,Byung-Gyu Chae,Sun-Jin Yun,Hyun-Tak Kim,Sang-Yeon Cho,N. Marie Jokerst,David R. Smith,Dimitri Basov +11 more
TL;DR: In this paper, a hybrid-metamaterial architecture is proposed for tuning a far-infrared resonance frequency with vanadium dioxide (VO2), a material whose optical properties can be strongly and quickly changed via external stimulus.
Journal ArticleDOI
Electronic correlations in the iron pnictides
M. Mumtaz Qazilbash,James Hamlin,Ryan Baumbach,Lijun Zhang,David J. Singh,M. B. Maple,Dimitri Basov +6 more
TL;DR: In this paper, an infrared and optical study on single crystals of the iron pnictide superconductor LaFePO was performed, and it was shown that correlations between electrons in these materials are just as strong as in some copper oxide and ruthenate superconductors.
Journal ArticleDOI
Electrodynamics of the vanadium oxides VO2 and V2O3
M. Mumtaz Qazilbash,Alexander Schafgans,Kenneth S. Burch,Sun-Jin Yun,Byung-Gyu Chae,B. J. Kim,Hyun-Tak Kim,Dimitri Basov +7 more
TL;DR: The optical and infrared properties of films of vanadium dioxide and vanadium sesquioxide have been investigated via ellipsometry and near-normal incidence reflectance measurements from far infrared to ultraviolet frequencies as discussed by the authors.
