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…
Mesoscopic Elastic Distortions in GaAs Quantum Dot Heterostructures
Anastasios Pateras, Joonkyu Park, Youngjun Ahn +9
Quantum devices formed in high-electron-mobility semiconductor heterostructures provide a route through which quantum mechanical effects can be exploited on length scales accessibl…
Role of temperature-dependent electron trapping dynamics in the optically driven nanodomain transformation in a PbTiO/SrTiO superlattice
Joonkyu Park, Youngjun Ahn, Jack A. Tilka +6
The spontaneously formed striped polarization nanodomain configuration of a PbTiO/SrTiO superlattice transforms to a uniform polarization state under above-bandgap illu…
