Quantitative models for excess carrier diffusion and recombination in STEM-EBIC experiments on semiconductor nanostructures
Tobias Meyer, Christoph Flathmann, David A. Ehrlich +4
The increased complexity and reduced size of (opto-)electronic devices demands for quantitative descriptions of excess carrier transport and recombination via various mechanisms. I…
Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands
V. Moshnyaga, Ch. Jooss, P. E. Blöchl +12
Energy conversion in materials can be considered as a sequence of elementary steps initiated by a primary excitation. While these steps are quite well understood in classical semic…
Atomic-Scale Investigation of an Asymmetric SrTiO Grain Boundary
Janina Malin Rybak, Jonas Arlt, Qian Ma +6
Grain boundaries (GBs) in oxide perovskites significantly influence their functional properties. This study examines the atomic-scale structure and composition of a faceted asymmet…
A thin film source in a solid-state diffusion experiment: CoO on SrTiO3
Qian Ma, Jan Erik Rybak, Natalie Jacqueline Ottinger +5
To realize a chemical diffusion experiment for simple quantitative analysis of one-dimensional diffusion profiles requires the fabrication of a planar and chemically sharp interfac…
