Metal-Insulator Transitions in β′-Cu V2O5 Mediated by Polaron Oscillation and Cation Shuttling

Silicon circuitry has dominated the semiconductor industry for decades but is constrained in its power efficiency by the Fermi-Dirac distribution of electron energies. Electron-correlated transition metal oxides exhibiting metal-to-insulator transitions (MITs) are excellent candidates for energy-efficient computation, which can further emulate the spiking behavior of biological neural circuitry. We demonstrate that β′-CuxV2O5 exhibits a...
