Interplay between polarization, strain and defect-pairs in Fe-doped SrMnO
Chiara Ricca, Ulrich Aschauer
Defect chemistry, strain, and structural, magnetic and electronic degrees of freedom constitute a rich space for the design of functional properties in transition metal oxides. Her…
Ferroelectricity promoted by cation/anion divacancies in SrMnO
Chiara Ricca, Danielle Berkowitz, Ulrich Aschauer
We investigate the effect of polar Sr-O vacancy pairs on the electric polarization of SrMnO (SMO) thin films using density functional theory (DFT) calculations. This is motivat…
Importance of surface oxygen vacancies for ultrafast hot carrier relaxation and transport in CuO
Chiara Ricca, Lisa Grad, Matthias Hengsberger +2
CuO has appealing properties as an electrode for photo-electrochemical water splitting, yet its practical performance is severely limited by inefficient charge extraction at th…
Surface and interface effects in oxygen deficient SrMnO thin films grown on SrTiO
Moloud Kaviani, Ulrich Aschauer
Complex oxide functionality, such as ferroelectricity, magnetism or superconductivity is often achieved in epitaxial thin-film geometries. Oxygen vacancies tend to be the dominant…
