Raman spectra of fine-grained materials from first principles
Maxim N. Popov, Jürgen Spitaler, Vignaswaran K. Veerapandiyan +3
Raman spectroscopy is an advantageous method for studying the local structure of materials, but the interpretation of measured spectra is complicated by the presence of oblique pho…
Architecture of nanoscale ferroelectric domains in GaMo4S8
Erik Neuber, Peter Milde, Adam Butykai +10
Local-probe imaging of the ferroelectric domain structure and auxiliary bulk pyroelectric measurements were conducted at low temperatures with the aim to clarify the essential aspe…
Local structure of relaxor ferroelectric SrBaNbO from pair distribution function analysis
M. Paściak, P. Ondrejkovic, P. Vanek +8
Neutron pair distribution function analysis and first principles calculations have been employed to study short-range correlations in heavily disordered dielectric material SrB…
Electron trapping by neutral pristine ferroelectric domain walls in BiFeO
Sabine Körbel, Jirka Hlinka, Stefano Sanvito
First-principles calculations for pristine neutral ferroelectric domain walls in BiFeO reveal that excess electrons are selectively trapped by the domain walls, while holes are…
Infrared, terahertz, and microwave spectroscopy of the soft and central modes in Pb(Mg1/3Nb2/3)O3
D. Nuzhnyy, J. Petzelt, V. Bovtun +4
From the new infrared (IR) reflectivity and time-domain terahertz (THz) spectra combined with available high-frequency dielectric data above the MHz range in a broad temperature ra…
Neutron scattering study of ferroelectric Sn2P2S6 under pressure
P. Ondrejkovic, M. Kempa, Y. Vysochanskii +4
Ferroelectric phase transition in the semiconductor Sn2P2S6 single crystal has been studied by means of neutron scattering in the pressure-temperature range adjacent to the anticip…
