Conductivity in Ferroelectric Barium Titanate : Electrons Versus Oxygen Vacancies [PDF]
, 2020 Mobile oxygen vacancies are increasingly widely believed to be responsible for electrical conductivity in perovskite oxide ferroelectrics. Here, this hypothesis is debated. The small-signal conductivity is investigated in oxygen-deficient films of barium

Variation of magnetic properties of Sr2FeMoO6 due to oxygen vacancies [PDF]
, 2022 Oxygen vacancies can be of utmost importance for improving or deteriorating physical properties of oxide materials. Here, we studied from first-principles the electronic and magnetic properties of oxygen vacancies in the double perovskite Sr2FeMoO6 (SFMO)

Localized versus itinerant states created by multiple oxygen vacancies in SrTiO3
New Journal of Physics, 2015 Oxygen vacancies in strontium titanate surfaces (SrTiO _3 ) have been linked to the presence of a two-dimensional electron gas with unique behavior. We perform a detailed density functional theory study of the lattice and electronic structure of SrTiO _3

Oxygen vacancies in strained
, 2017 We report the enthalpy of oxygen vacancy formation in thin films of electron-doped SrTiO3, under different degrees of epitaxial stress. We demonstrate that both compressive and tensile strain decrease this energy at a very similar rate and promote the ...
