Advancing Atom Probe Tomography of SrTiO: Measurement Methodology and Impurity Detection Limits
J. E. Rybak, J. Arlt, B. Gault +1
Strontium titanate (STO) possesses promising properties for applications in thermoelectricity, catalysis, fuel cells, and more, but its performance is highly dependent on stoichiom…
Nanoscale friction controlled by top layer thickness in [LaMnO]/[SrMnO] superlattices
Niklas A. Weber, Miru Lee, Florian Schönewald +4
We conducted lateral force microscopy measurements on seven [LaMnO]/[SrMnO] superlattices with varied layer thicknesses. We observe that the friction forces…
A criticial view on e occupancy as a descriptor for oxygen evolution catalytic activity in LiMnO nanoparticles
Florian Schönewald, Marco Eckhoff, Max Baumung +4
We investigate the effect of the surface electronic structure and composition of LiMnO nanoparticles on the electrocatalytic oxygen evolution reaction (OER). Scanning trans…
Closing the gap between theory and experiment for lithium manganese oxide spinels using a high-dimensional neural network potential
Marco Eckhoff, Florian Schönewald, Marcel Risch +3
Many positive electrode materials in lithium ion batteries include transition metals which are difficult to describe by electronic structure methods like density functional theory…
Switching friction at a manganite surface using electric fields
H. Schmidt, J. -O. Krisponeit, N. Weber +2
We report active control of the friction force at the contact between a nanoscale asperity and a LaCaMnO (LCMO) thin film using electric fields. We use fricti…
Tracking the diffusion-controlled lithiation reaction of LiMn2O4 by in-situ TEM
Torben Erichsen, Björn Pfeiffer, Vladimir Roddatis +1
Spinel lithium manganese oxide (LixMn2O4) is used as an active material in battery cathodes. It is a relatively inexpensive and environmentally friendly material, but suffers from…
