Random Forest Prediction of Crystal Structure from Electron Diffraction Patterns Incorporating Multiple Scattering
Samuel P. Gleason, Alexander Rakowski, Stephanie M. Ribet +5
Diffraction is the most common method to solve for unknown or partially known crystal structures. However, it remains a challenge to determine the crystal structure of a new materi…
Disentangling multiple scattering with deep learning: application to strain mapping from electron diffraction patterns
Joydeep Munshi, Alexander Rakowski, Benjamin H Savitzky +7
Implementation of a fast, robust, and fully-automated pipeline for crystal structure determination and underlying strain mapping for crystalline materials is important for many tec…
Automated Crystal Orientation Mapping in py4DSTEM using Sparse Correlation Matching
Colin Ophus, Steven E Zeltmann, Alexandra Bruefach +4
Crystalline materials used in technological applications are often complex assemblies composed of multiple phases and differently oriented grains. Robust identification of the phas…
Hydrocarbon Contamination in Angstrom-scale Channels
Ravalika Sajja, Yi You, Rongrong Qi +6
Nonspecific molecular adsorption like airborne contamination occurs on most surfaces including those of 2D materials and alters their properties. While the surface contamination is…
A Fast Algorithm for Scanning Transmission Electron Microscopy (STEM) Imaging and 4D-STEM Diffraction Simulations
Philipp M Pelz, Alexander Rakowski, Luis Rangel DaCosta +3
Scanning transmission electron microscopy (STEM) is an extremely versatile method for studying materials on the atomic scale. Many STEM experiments are supported or validated with…
Infrared-to-violet tunable optical activity in atomic films of GaSe, InSe, and their heterostructures
Daniel J. Terry, Viktor Zólyomi, Matthew Hamer +11
Two-dimensional semiconductors - atomic layers of materials with covalent intra-layer bonding and weak (van der Waals or quadrupole) coupling between the layers - are a new class o…
Transport of hydrogen isotopes through interlayer spacing in van der Waals crystals
S. Hu, K. Gopinadhan, A. Rakowski +7
Atoms start behaving as waves rather than classical particles if confined in spaces commensurate with their de Broglie wavelength. At room temperature this length is only about one…
Nanometer Resolution Elemental Mapping in Graphene-based TEM Liquid Cells
Daniel J. Kelly, Mingwei Zhou, Nick Clark +5
We demonstrate a new design of graphene liquid cell consisting of a thin lithographically patterned hexagonal boron nitride crystal encapsulated from both sides with graphene windo…
Phase segregation facilitates exfoliation of franckeite crystals to a single unit cell thickness
Matěj Velický, Peter S. Toth, Alexander M. Rakowski +8
Weak interlayer van der Waals interactions in bulk crystals facilitate their mechanical exfoliation to monolayer and few-layer two-dimensional (2D) materials, which exhibit strikin…
Magnetoresistance of vertical Co-graphene-NiFe junctions controlled by charge transfer and proximity-induced spin splitting in graphene
P. U. Asshoff, J. L. Sambricio, A. P. Rooney +9
Graphene is hailed as an ideal material for spintronics due to weak intrinsic spin-orbit interaction that facilitates lateral spin transport and tunability of its electronic proper…
