Inverse mask design for interference lithography using automatic differentiable wave propagation
Chuntian Cao, Jangwoon Sung, Jack Griffiths +9
Interference lithography (IL) is powerful for fabricating high-resolution periodic nanostructures, but designing masks to produce non-periodic patterns remains challenging. We intr…
Substrate-Mediated Evaporation and Stochastic Evolution of Supported Au Nanoparticles
Dmitri N. Zakharov, Xiaohui Qu, Hong Wang +6
We use in situ transmission electron microscopy with automated tracking to study supported gold nanoparticles (NPs) during high-temperature vacuum annealing. \rev{The average mass…
Unveiling Nano-scale Crystal Deformation using Coherent X-ray Dynamical Diffraction
Longlong Wu, David Yang, Wei Wang +5
Visualization of internal deformation fields in crystalline materials helps bridge the gap between theoretical models and practical applications. Applying Bragg coherent diffractio…
Dose-efficient Automatic Differentiation for Ptychographic Reconstruction
Longlong Wu, Shinjae Yoo, Yong S. Chu +2
Ptychography, as a powerful lensless imaging method, has become a popular member of the coherent diffractive imaging family over decades of development. The ability to utilize low-…
