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…
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…
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…
