Orbital-assisted metal-insulator transition in VO2.
We found direct experimental evidence for an orbital switching in the V 3d states across the metal-insulator transition in VO2. We have used soft-x-ray absorption spectroscopy at the V L2,3 edges as a sensitive local probe and have determined quantitatively the orbital polarizations. These results strongly suggest that, in going from the metallic to the insulating state, the orbital occupation ...
متن کاملMetal Insulator Transition
Metal Insulator transition(MIT) is characterized by the conductivity which will be zero in the insulator phase. In this term paper, we focus on Mott insulator, and a simple theoritical way to describe this MIT is the Hubbard Model .Finally, we will look at the experiments of Mott insulator transition .
متن کاملMetal-insulator Transition (scaling Theory)
In this paper I brieey discuss the concepts of localization and metal-insulator transition. The phenomenological description of the conducting properties depending on the dimensionality and disorder, and the physical arguments for the scaling-function are presented. The conducting properties of the 3D system near the critical point of the metal-insulator transition predicted by this scaling mod...
متن کاملCarbon kagome lattice and orbital-frustration-induced metal-insulator transition for optoelectronics.
A three-dimensional elemental carbon kagome lattice, made of only fourfold-coordinated carbon atoms, is proposed based on first-principles calculations. Despite the existence of 60° bond angles in the triangle rings, widely perceived to be energetically unfavorable, the carbon kagome lattice is found to display exceptional stability comparable to that of C(60). The system allows us to study the...
