Bias-triggered conductivity relaxation (BCR): a unique tool to simultaneously investigate thermodynamics, kinetics and electrostatic effects of oxygen reactions in MIEC thin films
Alexander Stangl, Alexander Schmid, Adeel Riaz +2
Mixed ionic electronic transfer (MIET) reactions, such as the oxygen reduction reaction (ORR) at oxide surfaces, are of paramount importance to manifold technologically highly rele…
Fast track to the overdoped regime of superconducting YBa2Cu3O7-δ thin films via electrochemical oxidation
Alexander Stangl, Aiswarya Kethamkuzhi, Hervé Roussel +5
High temperature superconductors, especially YBaCuO (YBCO), are considered a key enabling technology towards a clean energy future. Hole doping in YBCO is a prereq…
Oxygen incorporation in YBaCuO thin films: surface activation and degradation
Alexander Stangl, Xavier Obradors, Anna Palau +2
The oxygen off-stoichiometry plays a pivotal role for the physical properties of superconducting oxides. Yet, there is a lack of knowledge on the fundamental processes of oxygen in…
Investigating oxides by electrochemical projection of the oxygen off-stoichiometry diagram onto a single sample
Alexander Stangl, Alexander Schmid, Adeel Riaz +10
The oxygen stoichiometry is an essential key to tune functional properties of advanced oxide materials and thus has motivated numerous studies of the oxygen off-stoichiometry diagr…
