Insights into Chemical and Structural Order at Planar Defects in a Functional Oxide Using Multislice Electron Ptychography
Menglin Zhu, Michael Xu, Yu Yun +7
Switchable order parameters in ferroic materials are essential for functional electronic devices, yet disruptions of the ordering can take the form of planar boundaries or defects…
An atomistic model of electronic polarizability for calculation of Raman scattering from large-scale MD simulations
Atanu Paul, Anthony Ruffino, Stefan Masiuk +2
The application of molecular dynamics (MD) simulations to the interpretation of Raman scattering spectra is hindered by inability of atomistic simulations to account for the dynami…
Strong Bulk Photovoltaic Effect in Planar Barium Titanate Thin Films
Andrew L. Bennett-Jackson, Or Shafir, A. R. Will-Cole +9
The bulk photovoltaic effect (BPE) leads to the generation of a photocurrent from an asymmetric material. Despite drawing much attention due to its ability to generate photovoltage…
Advancing from phenomenological to predictive theory of ferroelectric oxide solution properties through consideration of domain walls
Atanu Samanta, Suhas Yadav, Or Shafir +9
Prediction of properties from composition is a fundamental goal of materials science and can greatly accelerate development of functional materials. It is particularly relevant for…
The shift photovoltaic current and magnetically-induced bulk photocurrent in piezoelectric sillenite crystals
Aaron M. Burger, Lingyuan Gao, Radhe Agarwal +4
Recently, it has been shown how shift and ballistic currents in piezoelectric sillenite crystals BiGeO and BiSiO can be separated experimentally under t…
Surface- and strain-tuning of the optical dielectric function in epitaxially grown CaMnO3
Dominic Imbrenda, Dongyue Yang, Hongwei Wang +6
We report a strong thickness dependence of the complex frequency-dependent optical dielectric function in epitaxial CaMnO3(001) thin films on SrTiO3(001), LaAlO3(001), and SrLaAlO4…
Modiffied Schottky emission to explain thickness dependence and slow depolarization in BaTiO nanowires
Y. Qi, J. M. P. Martirez, Wissam A. Saidi +4
We investigate the origin of the depolarization rates in ultrathin adsorbate-stabilized ferroelectric wires. By applying density functional theory calculations and analytic modelin…
A Comprehensive Multiphonon Spectral Analysis in MoS2
Tsachi Livneh, Jonathan E. Spanier
We present a comprehensive multiphonon Raman and complementary infrared analysis for bulk and monolayer MoS2.For the bulk the analysis consists of symmetry assignment from which we…
Normal Mode Determination of Perovskite Crystal Structures with Octahedral Rotations: Theory and Applications
Mohammad A. Islam, James M. Rondinelli, Jonathan E. Spanier
Nuclear site analysis methods are used to enumerate the normal modes of perovskite polymorphs with octahedral rotations. We provide the modes of the fourteen subgroups of…
