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…
How to cleave cubic perovskite oxides
Igor Sokolović, Michael Schmid, Ulrike Diebold +1
Surfaces of cubic perovskite oxides attract significant attention for their physical tunability and high potential for technical applications. Bulk-terminated surfaces are desirabl…
Duality and degeneracy lifting in two-dimensional electron liquids on SrTiO(001)
Igor Sokolović, Eduardo B. Guedes, Thomas P. van Waas +7
Two-dimensional electron liquids (2DELs) have increasing technological relevance for ultrafast electronics and spintronics, yet significant gaps in their fundamental understanding…
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…
Interaction of surface cations of cleaved mica with water in vapor and liquid forms
Giada Franceschi, Sebastian Brandstetter, Jan Balajka +5
Natural minerals contain ions that become hydrated when they come into contact with water in vapor and liquid forms. Muscovite mica -- a common phyllosilicate with perfect cleavage…
Resolving the intrinsic short-range ordering of K ions on cleaved muscovite mica
Giada Franceschi, Pavel Kocán, Andrea Conti +8
Muscovite mica, KAl(SiAl)O(OH), is a common layered phyllosilicate with perfect cleavage planes. The atomically flat surfaces obtained through cleaving lend them…
