Importance of surface oxygen vacancies for ultrafast hot carrier relaxation and transport in Cu $_{2}$ O

Chiara Ricca, Lisa Grad, Matthias Hengsberger +2

Cu $_{2}$ O has appealing properties as an electrode for photo-electrochemical water splitting, yet its practical performance is severely limited by inefficient charge extraction at th…

Suitability of $β$ -Mn $_{2}$ V $_{2}$ O $_{7}$ / $β$ -Cu $_{2}$ V $_{2}$ O $_{7}$ solid solutions for photocatalytic water-splitting

Silviya Ninova, Michal Strach, Raffaella Buonsanti +1

The pyrovanadates $β$ -Mn $_{2}$ V $_{2}$ O $_{7}$ and $β$ -Cu $_{2}$ V $_{2}$ O $_{7}$ were previously investigated as photoanode materials for water splitting. Neither of them, however, was found to be…

Local polarization in oxygen-deficient LaMnO $_{3}$ induced by charge localization in the Jahn-Teller distorted structure

Chiara Ricca, Nicolas Niederhauser, Ulrich Aschauer

The functional properties of transition metal perovskite oxides are known to result from a complex interplay of magnetism, polarization, strain, and stoichiometry. Here, we show th…

Self-consistent DFT+ $U$ + $V$ study of oxygen vacancies in SrTiO $_{3}$

Chiara Ricca, Iurii Timrov, Matteo Cococcioni +2

Contradictory theoretical results for oxygen vacancies in SrTiO $_{3}$ (STO) were often related to the peculiar properties of STO, which is a $d^{0}$ transition metal oxide with mixed i…

Density functional theory study of the oxygen evolution activity on Sr $_{2}$ TaO $_{3}$ N surfaces

Maria Bouri, Ulrich Aschauer

Solar water splitting has attracted much attention as a clean and renewable route to produce hydrogen fuel. Since the oxygen evolution half-reaction (OER) requires high overpotenti…

Nitrogen loss and oxygen evolution reaction activity of perovskite oxynitrides

Hassan Ouhbi, Ulrich Aschauer

Perovskite oxynitride photocatalysts were reported by experiment to evolve small amounts of N $_{2}$ due to the self-oxidation of nitrogen ions by photo-generated holes. The N $_{2}$ evo…
