Strategies for Deploying AI Agents in Production at Scientific User Facilities
Ming Du, Xiangyu Yin, Michael Prince +40
Agentic artificial intelligence (AI) is moving beyond research demonstrations toward production use at scientific user facilities, including light sources, neutron sources, nanosci…
Pty-Chi: A PyTorch-based modern ptychographic data analysis package
Ming Du, Hanna Ruth, Steven Henke +11
Ptychography has become an indispensable tool for high-resolution, non-destructive imaging using coherent light sources. The processing of ptychographic data critically depends on…
Three-dimensional Hard X-ray Ptychographic Reflectometry Imaging on Extended Mesoscopic Surface Structures
Peco Myint, Ashish Tripathi, Michael J. Wojcik +7
Many nano and quantum devices, with their sizes often spanning from millimeters down to sub-nanometer, have intricate low-dimensional, non-uniform, or hierarchical structures on su…
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…
Multislice forward modeling of Coherent Surface Scattering Imaging on surface and interfacial structures
Peco Myint, Miaoqi Chu, Ashish Tripathi +6
To study nanostructures on substrates, surface-sensitive reflection-geometry scattering techniques such as grazing incident small angle x-ray scattering are commonly used to yield…
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…
