Probing Non-Equilibrium Grain Boundary Dynamics with XPCS and Domain-Adaptive Machine Learning
Mouyang Cheng, Bowen Yu, Chu-Liang Fu +14
Grain-boundary (GB) dynamics control the stability, mechanical, and functional response of nanocrystalline materials, but direct experimental access to their slow non-equilibrium m…
A Fully Convolutional Approach to Denoising 2D Correlation Spectra
Nisar Nellikunnummel, Andi M Barbour, Lutz Wiegart +2
We present a fully convolutional denoising autoencoder (FC-DAE) tailored for two-dimensional representations of dynamic correlations that is applicable to many experimental techniq…
Metastable short-range charge order in superconducting CuxTiSe2
Thomas Sutter, Colleen Lindenau, Shivani Sharma +5
In a vast array of materials, including cuprates, transition metal dichalcogenides (TMDs) and rare earth tritellurides, superconductivity is found in the vicinity of short-range ch…
Coherent X-ray Spectroscopy Elucidates Nanoscale Dynamics of Plasma-Enhanced Thin-Film Growth
Peco Myint, Jeffrey M. Woodward, Chenyu Wang +6
Sophisticated thin film growth techniques increasingly rely on the addition of a plasma component to open or widen a processing window, particularly at low temperatures. However, t…
Local step-flow dynamics in thin film growth with desorption
Xiaozhi Zhang, Jeffrey G. Ulbrandt, Peco Myint +6
Desorption of deposited species plays a role in determining the evolution of surface morphology during crystal growth when the desorption time constant is short compared to the tim…
Machine Learning Enhances Algorithms for Quantifying Non-Equilibrium Dynamics in Correlation Spectroscopy Experiments to Reach Frame-Rate-Limited Time Resolution
Tatiana Konstantinova, Lutz Wiegart, Maksim Rakitin +2
Analysis of X-ray Photon Correlation Spectroscopy (XPCS) data for non-equilibrium dynamics often requires manual binning of age regions of an intensity-intensity correlation functi…
Noise Reduction in X-ray Photon Correlation Spectroscopy with Convolutional Neural Networks Encoder-Decoder Models
Tatiana Konstantinova, Lutz Wiegart, Maksim Rakitin +2
Like other experimental techniques, X-ray Photon Correlation Spectroscopy is subject to various kinds of noise. Random and correlated fluctuations and heterogeneities can be presen…
Measurement of Ehrlich-Schwoebel barrier contribution to the self-organized formation of ordered surface patterns on Ge(001)
Peco Myint, Denise Erb, Xiaozhi Zhang +6
Normal incidence 1 keV Ar ion bombardment leads to amorphization and ultrasmoothing of Ge at room temperature, but at elevated temperatures the Ge surface remains crystalline a…
Nanoscale dynamics during self-organized ion beam patterning of Si: II. Kr Bombardment
Peco Myint, Karl F. Ludwig, Lutz Wiegart +4
Despite extensive study, fundamental understanding of self-organized patterning by broad-beam ion bombardment is still incomplete and controversial. Understanding the nanopatternin…
Nanoscale dynamics during self-organized ion beam patterning of Si: I. Ar Bombardment
Peco Myint, Karl F. Ludwig, Lutz Wiegart +4
Coherent grazing-incidence small-angle X-ray scattering is used to investigate the average kinetics and the fluctuation dynamics during self-organized nanopatterning of silicon by…
Coherent X-ray measurement of step-flow propagation during growth on polycrystalline thin film surfaces
Randall L. Headrick, Jeffrey G. Ulbrandt, Peco Myint +6
The properties of artificially grown thin films are strongly affected by surface processes during growth. Coherent X-rays provide an approach to better understand such processes an…
Three-dimensional coherent X-ray diffraction imaging of a whole, frozen-hydrated cell
Jose A. Rodriguez, Rui Xu, Chien-Chun Chen +13
A structural understanding of whole cells in three dimensions at high spatial resolution remains a significant challenge and, in the case of X-rays, has been limited by radiation d…
