Giant photoinduced lattice distortion in oxygen-vacancy ordered SrCoO2.5 thin films
Bingbing Zhang, Xu He, Jiali Zhao +8
Despite of the tremendous efforts spent on the oxygen vacancy migration in determining the property optimization of oxygen-vacancy enrichment transition metal oxides, few has focus…
Insulating phase at low temperature in ultrathin La0.8Sr0.2MnO3 films
Yaqing Feng, Kui-juan Jin, Lin Gu +9
Metal-insulator transition is observed in the La0.8Sr0.2MnO3 thin films with thickness larger than 5 unit cells. Insulating phase at lower temperature appeared in the ultrathin fil…
Engineering charge ordering into multiferroicity
Xu He, Kui-juan Jin
Multiferroic materials have attracted great interests but are rare in nature. In many transitional metal oxides, charge ordering and magnetic ordering coexist, so that a method of…
Persisting of Polar Distortion with Electron Doping in Lone-Pair Driven Ferroelectrics
Xu He, Kui-juan Jin
Free electrons can screen out long-range Coulomb interaction and destroy the polar distortion in some ferroelectric materials, whereas the coexistence of polar distortion and metal…
Ferroelectric Control of Metal-Insulator Transition
Xu He, Kui-juan Jin, Chen Ge +2
We propose a method of controlling the metal-insulator transition of one perovskite material at its interface with a another ferroelectric material based on first principle calcula…
Evolution of the electronic and lattice structure with carrier injection in BiFeO
Xu He, Kui-juan Jin, Hai-zhong Guo +1
We report a density functional study on the evolution of the electronic and lattice structure in BiFeO with injected electrons and holes. First, the self-trapping of electrons…
