Instrument for in situ hard x-ray nanobeam characterization during epitaxial crystallization and materials transformations
Samuel D. Marks, Peiyu Quan, Rui Liu +5
Solid-phase epitaxy (SPE) and other three-dimensional epitaxial crystallization processes pose challenging structural and chemical characterization problems. The concentration of d…
Dynamic Tilting of Ferroelectric Domain Walls via Optically Induced Electronic Screening
Youngjun Ahn, Arnoud S. Everhardt, Hyeon Jun Lee +8
Optical excitation perturbs the balance of phenomena selecting the tilt orientation of domain walls within ferroelectric thin films. The high carrier density induced in a low-strai…
Dynamical Scattering in Coherent Hard X-Ray Nanobeam Bragg Diffraction
A. Pateras, J. Park, Y. Ahn +5
Unique intensity features arising from dynamical diffraction arise in coherent x-ray nanobeam diffraction patterns of crystals having thicknesses larger than the x-ray extinction d…
Stressor-Layer-Induced Elastic Strain Sharing in SrTiO3 Complex Oxide Sheets
J. A. Tilka, J. Park, Y. Ahn +3
A precisely selected elastic strain can be introduced in submicron-thick single-crystal SrTiO3 sheets using a silicon nitride stressor layer. A conformal stressor layer deposited u…
Three-dimensional phonon population anisotropy in silicon nanomembranes
Kyle M. McElhinny, Gokul Gopalakrishnan, Martin V. Holt +2
Nanoscale single-crystals possess modified phonon dispersions due to the truncation of the crystal. The introduction of surfaces alters the population of phonons relative to the bu…
Domain alignment within ferroelectric/dielectric PbTiO/SrTiO superlattice nanostructures
J. Park, J. Mangeri, Q. Zhang +7
The ferroelectric domain pattern within lithographically defined PbTiO3/SrTiO3 ferroelectric/dielectric heteroepitaxial superlattice nanostructures is strongly influenced by the ed…
