Modeling nonlinear optical interactions of focused beams in bulk crystals and thin films: A phenomenological approach
Kai J. Spychala, Zeeshan H. Amber, Lukas M. Eng +1
Coherent nonlinear optical micro-spectroscopy is a frequently used tool in modern material science, as it is sensitive to many different local observables, which comprise, among ot…
Vibrational properties of LiNbO and LiTaO under uniaxial stress
Ekta Singh, Mike N. Pionteck, Sven Reitzig +4
Structural strain severely impacts material properties such as the linear and non-linear optical response. Moreover, strain plays a key role, e.g., in the physics of ferroelectrics…
Impact of 3D curvature on the polarization orientation in non-Ising domain walls
Ulises Acevedo-Salas, Boris Croes, Yide Zhang +11
Ferroelectric domain boundaries are quasi-two-dimensional functional interfaces with high prospects for nanoelectronic applications. Despite their reduced dimensionality, they can…
Tuning the domain wall conductivity in bulk lithium niobate by uniaxial stress
Ekta Singh, Henrik Beccard, Zeeshan H. Amber +4
Conductive domain walls (CDWs) in insulating ferroelectrics have recently attracted considerable attention due to their unique topological, optical, and electronic properties, and…
Large Hall electron mobilities in head-to-head BaTiO-domain walls
Henrik Beccard, Benjamin Kirbus, Elke Beyreuther +4
Strongly charged head-to-head (H2H) domain walls (DWs) that are purposely engineered along the [110] crystallographic orientation into ferroelectric BaTiO single crystals have…
