Unraveling the Mott-Peierls intrigue in vanadium dioxide [PDF]
Physical Review Research, 2020 Vanadium dioxide is one of the most studied strongly correlated materials. Nonetheless, the intertwining between electronic correlation and lattice effects has precluded a comprehensive description of the rutile metal to monoclinic insulator transition, in turn triggering a longstanding "the chicken or the egg" debate about which comes first, the Mott ...

Magnetic-field-induced insulator–metal transition in W-doped VO2 at 500 T
Nature Communications, 2020 Vanadium dioxide exhibits a metal-insulator (MI) transition. The mechanism driving this behaviour has long been a subject of debate. Here, the authors show that the MI transition in heavily doped vanadium dioxide can be driven by a magnetic field ...

Vanadium dioxide based plasmonic modulators
Optics Express, 2012 Actively tunable metal-insulator-metal waveguides that employ vanadium dioxide films as the active medium are analyzed numerically. Vanadium dioxide exhibits strong contrast between the optical properties of its insulating and metallic phases. In particular, the large optical absorption in the metallic phase makes it straightforward to implement ...

Vanadium doped tin dioxide as a novel sulfur dioxide sensor
Talanta, 2008 Considering the short-term exposure limit of SO2 to be 5 ppm, we first time report that semiconductor sensors based on vanadium doped SnO2 can be used for SO2 leak detection because of their good sensitivity towards SO2 at concentrations down to 5 ppm. Such sensors are quite selective in presence of other gases like carbon monoxide, methane and butane.
