Scanning X-ray Diffraction Microscopy for Diamond Quantum Sensing
Mason C. Marshall, David F. Phillips, Matthew J. Turner +6
Understanding nano- and micro-scale crystal strain in CVD diamond is crucial to the advancement of diamond quantum technologies. In particular, the presence of such strain and its…
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

Correlated nanoscale analysis of the emission from wurtzite versus zincblende (In,Ga)As/GaAs nanowire core-shell quantum wells
Jonas Lähnemann, Megan O. Hill, Jesús Herranz +12
While the properties of wurtzite GaAs have been extensively studied during the past decade, little is known about the influence of the crystal polytype on ternary (In,Ga)As quantum…
Residual Nanoscale Strain in Cesium Lead Bromide Perovskite Reduces Stability and Alters Local Band Gap
Xueying Li, Yanqi Luo, Martin Holt +2
Using nanoprobe X-ray diffraction microscopy, we investigate the relationship between residual strains from crystal growth in CsPbBr thin film crystals, their stability, and lo…
Time-resolved x-ray microscopy for materials science
Haidan Wen, Mathew J. Cherukara, Martin V. Holt
X-ray microscopy has been an indispensable tool to image nanoscale properties for materials research. One of its recent advances is to extend microscopic studies to the time domain…
Non-equilibrium phase precursors to the insulator-metal transition in V2O3
Andrej Singer, Juan Gabriel Ramirez, Ilya Valmianski +11
The discovery of novel phases of matter is at the core of modern physics. In quantum materials, subtle variations in atomic-scale interactions can induce dramatic changes in macros…
Critical phenomena of nano phase evolution in a first order transition
Yongseong Choi, David J. Keavney, Martin V. Holt +5
First order phase transitions occur discretely from one state to another, however they often display continuous behavior. To understand this nature, it is essential to probe how th…
