VO 2 , of interest for decades due to both its phenomenology and its potential applications, has a monoclinic distortion of the rutile crystal structure at ambient temperature that is coupled to its metal-insulator transition (MIT). In contrast, RuO 2 has three electrons more per formula unit, is a metallic conductor, and has an undistorted rutile structure. Here we report a systematic study of Ru-doped VO 2 (V 1-x Ru x O 2 , 0.01 ≤ x ≤ 0.9); generally characterizing its crystal structure…

Insulator to correlated metal transition in V1?xMoxO2

Although many materials display the transition from insulating to metallic behavior on doping, only a few, such as VO2, have the right combination of crystal structure and physical properties to

This contribution on the V(1-x)W(x)O(2) system is attempt to clarify the origin of the MIT induced by tungsten doping and investigates the electronic structure and the main effect of the internal stress on the vanadium local structure.

Suppression of Metal-Insulator Transition in VO2 by Electric Field–Induced Oxygen Vacancy Formation

It is found that electrolyte gating of epitaxial thin films of VO2 suppresses the metal-to-insulator transition and stabilizes the metallic phase to temperatures below 5 kelvin, even after the ionic liquid is completely removed.

Composition-dependent charge transfer and phase separation in the V1-xRexO2 solid solution.

Composed X-ray photoelectron spectroscopy studies showed that an increased amount of Re leads to a change in the Re valence state from solely Re6+ at a low doping level via mixed-valence states Re4+/Re6+ for at least 0.03, while intermediate compositions are subjected to a phase separation, presumably due to different valence states of Re.

Understanding the nature of the kinetic process in a VO2 metal-insulator transition.

The temperature-dependent in situ x-ray absorption fine structure measurement and density-functional theory calculations have revealed that the monoclinic-to-tetragonal phase transition of VO2 near the critical temperature is characterized by a sharp decrease of the twisting angle δ of the nearest V-V coordination.

Electronic Properties of V O 2 near the Semiconductor-Metal Transition

Optical, thermal, magnetic, and transport properties of V${\mathrm{O}}_{2}$ in the vicinity of the semiconductor-metal transition temperature of 68\ifmmode^\circ\else\textdegree\fi{}C are discussed

Orbital-assisted metal-insulator transition in VO2.

These results strongly suggest that, in going from the metallic to the insulating state, the orbital occupation changes in a manner that charge fluctuations and effective bandwidths are reduced, that the system becomes more one dimensional and more susceptible to a Peierls-like transition.
