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…

Real-space investigation of polarons in hematite Fe2O3
Jesus Redondo, Michele Reticcioli, Vit Gabriel +17
In polarizable materials, electronic charge carriers interact with the surrounding ions, leading to quasiparticle behaviour. The resulting polarons play a central role in many mate…
