A solid-solution approach for room-temperature bulk plasticity in KTa1-xNbxO3
Alexander Frisch, Jiawen Zhang, Martin Setvin +3
Dislocations are being engineered into perovskite oxides to harvest versatile functional properties. One major bottleneck, however, persists: perovskite oxides that can be engineer…
Photoexcited Hole States at the SrTiO3(001) Surface Imaged with Noncontact AFM
Igor Sokolovic, Florian Ellinger, Aji Alexander +8
The behaviour of excess charges in ionic lattices, such as the formation of polarons and charge trapping at defect sites, influences the physical and chemical properties of materia…
Competition between clustering and dispersion of cobalt atoms on perovskite surfaces: SrTiO3(001) and KTaO3(001)
Aji Alexander, Pankaj Kumar Samal, Llorenc Albons +8
Perovskite oxides are attractive for reactions in photo/electrocatalytic schemes, and extrinsic doping is a common strategy for tuning their properties. It is widely known that ext…
A Multi-Technique Study of C2H4 Adsorption on a Model Single-Atom Rh1 Catalyst
Chunlei Wang, Panukorn Sombut, Lena Puntscher +9
Single-atom catalysts are potentially ideal model systems to investigate structure-function relationships in catalysis, if the active sites can be uniquely determined. In this work…
Room-temperature bulk plasticity and tunable dislocation densities in KTaO3
Xufei Fang, Jiawen Zhang, Alexander Frisch +4
We report room-temperature bulk plasticity mediated by dislocations in single-crystal cubic KTaO3, contrasting the conventional knowledge that single-crystal KTaO3 is susceptible t…
Machine Learning Based Prediction of Polaron-Vacancy Patterns on the TiO(110) Surface
Viktor C. Birschitzky, Igor Sokolovic, Michael Prezzi +5
The multifaceted physics of oxides is shaped by their composition and the presence of defects, which are often accompanied by the formation of polarons. The simultaneous presence o…
