Atomistic approach to simulate kink migration and kink-pair formation in silicon: The kinetic activation-relaxation technique
(Journal article; Peer reviewed, 2019)The energy conversion efficiency of solar cells based on multicrystalline silicon is greatly deteriorated by dislocations. However, an in-depth understanding on the dislocation motion dynamics down to atomic scale is still ... -
Determining fundamental properties from diffraction: Electric field induced strain and piezoelectric coefficient
(Peer reviewed; Journal article, 2019)Neutron powder diffraction was used in operando to determine the macroscopic strain and piezoelectric coefficient as a function of applied electric field in a technically relevant actuator material. We were able to ... -
First-principles study of topologically protected vortices and ferroelectric domain walls in hexagonal YGaO3
(Peer reviewed; Journal article, 2020)Ferroelectric behavior on the meso- and macroscopic scale depends on the formation and dynamics of domains and controlling the domain patterns is imperative to device performance. While density functional theory (DFT) ... -
Local control of improper ferroelectric domains in YMnO 3
(Peer reviewed; Journal article, 2020)Improper ferroelectrics are described by two order parameters: a primary one, driving a transition to long-range distortive, magnetic, or otherwise nonelectric order, and the electric polarization, which is induced by the ... -
Low-energy properties of electrons and holes in CuFeS2
(Peer reviewed; Journal article, 2022)The antiferromagnetic semiconductor CuFeS2 belongs to a magnetic symmetry class that is of interest for spintronics applications. In addition, its crystal lattice is compatible with Si, making it possible to integrate it ... -
Uniaxial Néel vector control in perovskite oxide thin films by anisotropic strain engineering
(Peer reviewed; Journal article, 2021)Antiferromagnetic (AF) thin films typically exhibit a multidomain state, and control of the AF Néel vector is challenging, as AF materials are robust to magnetic perturbations. In this paper, uniaxial Néel vector control ...
