Anisotropic Defect Diffusion in Layered CsPbBrI Perovskites
Konrad Wilke, Mike Pols, Titus S. van Erp +2
Mixed-halide perovskites offer a route to enhance phase stability and modify optoelectronic properties. Here, we use large-scale molecular dynamics simulations with a reactive forc…
Chiral Surface Phonons
Mike Pols, Nicola A. Spaldin
We use symmetry arguments combined with density functional theory to demonstrate that all surfaces of crystalline materials host surface phonons that are chiral. As model system, w…
Lattice excitations with finite polarization and magnetization
Mike Pols, Carl P. Romao, Dominik M. Juraschek
Ferrons are a type of quasiparticle corresponding to elementary excitations of the ferroelectric order. Analogously to how magnons modulate and transport magnetization, ferrons mod…
Halide diffusion in mixed-halide perovskites and heterojunctions
Viren Tyagi, Mike Pols, Geert Brocks +1
Migration of halide defects guides ion transport in metal halide perovskites and controls the kinetics of halide mixing and phase separation. We study the diffusion of halide vacan…
Impact of Metal Cation on Chiral Properties of 2D Halide Perovskites
Mike Pols, Helena Boom, Geert Brocks +2
Chiral two-dimensional (2D) halide perovskites are formed by embedding chiral organic cations in a perovskite crystal structure. The chirality arises from distortions of the 2D met…
Chiral Phonons in 2D Halide Perovskites
Mike Pols, Geert Brocks, SofÃa Calero +1
Phonons in chiral crystal structures can be circularly polarized, making them chiral. Chiral phonons carry angular momentum, which is observable in heat currents, and, via coupling…
