Dynamic Distortions of Quasi-2D Ruddlesden-Popper Perovskites at Elevated Temperatures: Influence on Thermal and Electronic Properties
Raisa-Ioana Biega, Menno Bokdam, Kai Herrmann +5
Ruddlesden-Popper hybrid halide perovskite are quasi-two-dimensional materials with a layered structure and structural dynamics that are determined by the interplay between the org…

Quantum-Probe Field Microscopy of Ultrafast Terahertz Excitations
Moritz B. Heindl, Nicholas Kirkwood, Tobias Lauster +4
Rapid evolutions of microscopic fields govern the majority of elementary excitations in condensed matter and drive microelectronic currents at increasing frequencies. Beyond nomina…

Contact-based and spheroidal vibrational modes of a hexagonal monolayer of microspheres on a substrate
A. Vega-Flick, R. A. Duncan, S. P. Wallen +6
We study acoustic modes of a close-packed hexagonal lattice of spheres adhered to a substrate, propagating along a high-symmetry direction. The model, accounting for both normal an…
