Mott Transition in VO <sub>2</sub> Revealed by Infrared Spectroscopy and Nano-Imaging
Mott Transition in VO <sub>2</sub> Revealed by Infrared Spectroscopy and Nano-Imaging
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 doping or heating, the resulting conducting state can be radically different from that characterized by free electrons in conventional metals. We report on the electronic properties …
