Ferrimagnetism induced by thermal vibrations in oxygen-deficient manganite heterostructures
Moloud Kaviani, Chiara Ricca, Ulrich Aschauer
Super-exchange most often leads to antiferromagnetim in transition-metal perovskite oxides, yet ferromagnetism or ferrimagnetism would be preferred for many applications, for examp…
Photochemical Anisotropy and Direction-dependent Optical Absorption in Semiconductors
Chiara Ricca, Ulrich Aschauer
Photochemical reactions on semiconductors are anisotropic, since they occur with different rates on surfaces of different orientation. Understanding the origin of this anisotropy i…
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…
Local polarization in oxygen-deficient LaMnO 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…
