Anharmonic Host Lattice Dynamics Enable Fast Ion Conduction in Superionic AgI
Thomas M. Brenner, Christian Gehrmann, Roman Korobko +3
Basic understanding of the driving forces of ion conduction in solids is critical to the development of new solid-state ion conductors. Physical understanding of ion conduction is…
Dynamic Shortening of Disorder Potentials in Anharmonic Halide Perovskites
Christian Gehrmann, David A. Egger
Halide perovskites are semiconductors that exhibit sharp optical absorption edges and small Urbach energies allowing for efficient collection of sunlight in thin-film photovoltaic…
Structure and Binding in Halide Perovskites: Analysis of Static and Dynamic Effects from Dispersion-Corrected Density Functional Theory
Hubert Beck, Christian Gehrmann, David A. Egger
We investigate the impact of various levels of approximation in density functional theory calculations for the structural and binding properties of the prototypical halide perovski…
