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…
Spectral self-adaptive absorber/emitter for harvesting energy from the sun and outer space
Xianze Ao, Bowen Li, Bin Zhao +11
The sun (~6000 K) and outer space (~3 K) are the original heat source and sink for human beings on Earth. The energy applications of absorbing solar irradiation and harvesting the…
