Manipulating the anisotropic phase separation in strained VO2 epitaxial films by nanoscale ion-implantation
Changlong Hu, Liang Li, Xiaolei Wen +5
Manipulating the strain induced poly-domains and phase transition in correlated oxide material are important for high performance devices fabrication. Though the electronic transpo…
Atomic origin for hydrogenation promoted bulk oxygen vacancies removal in vanadium dioxide
Bowen Li, Min Hu, Hui Ren +5
Oxygen vacancies (VO), a common type of point defects in metal oxides materials, play important roles on the physical and chemical properties. To obtain stoichiometric oxide crysta…
Electron Correlation driven Metal-Insulator transition in Strained and Disordered VO2 films
Alessandro D'Elia, Cesare Grazioli, Albano Cossaro +6
The Metal-Insulator transition (MIT) in VO2 is characterized by the complex interplay among lattice, electronic and orbital degrees of freedom. In this contribution we investigated…
Spatially-resolved insulator-metal transition for rewritable optical gratings
Yuliang Chen, Changlong Hu, Liyan Xie +7
Doping is an effective way to tune the property of metal oxides1-5, for achieving functional oxide electronics6-8. Previously we developed a controllable hydrogen doping technology…
Wafer-size VO2 film prepared by water-vapor oxidant
H. Ren, B. Li, X. Zhou +7
The growth of wafer-scale and uniform monoclinic VO2 film was a challenge if considering the multivalent vanadium atom and the various phase structures of VO2 compound. Directly ox…
Electron-proton Co-doping Induced Metal-insulator Transition in VO2 Film via Surface Self-assembled Ascorbic Acid Molecules
Bowen Lia, Liyan Xieb, Zhaowu Wang +7
Charge doping is an effective way to induce metal-insulate transition (MIT) in correlated materials for many important utilizations, which is however practically limited by problem…
