Mapping Order in Semicrystalline Polymers using Machine Learning of Nanobeam Electron Diffraction
Nicholas Marchese, Arthur R. C. McCray, Yael Tsarfati +4
Organic mixed ionic electronic conductors (OMIECs) are a promising class of polymer materials for applications spanning neuromorphic computation to energy efficient electronics and…
Topochemically-engineered coexistence of charge and spin orders in intercalated endotaxial heterostructures
Samra HusremoviÄ, Wanlin Zhang, Medha Dandu +10
Correlated electron systems that host multiple electronic orders offer routes to multifunctional quantum materials, but strong competition between these orders often prevents their…
Nanocrystal Geometry Governs Phase Transformation Pathways in Palladium Hydride
Daewon Lee, Sam Oaks-Leaf, Hyeonjong Ma +14
Pathways and structural dynamics of phase transformations impact performance of materials in energy and information storage technologies. Palladium hydride () nanoc…
Multi-angle precession electron diffraction (MAPED): a versatile approach to 4D-STEM precession
Stephanie M. Ribet, Rohan Dhall, Colin Ophus +1
Precession of a converged beam during acquisition of a 4D-STEM dataset improves strain, orientation, and phase mapping accuracy by averaging over continuous angles of illumination.…
Neutral but Impactful: Gallium Cluster-Induced Nanopores from Beam-Blanked Gallium Ion Sources
Dana O. Byrne, Stephanie M. Ribet, Karen C. Bustillo +2
Neutral atoms emitted from liquid metal ion sources are an often-overlooked source of contamination and damage in focused ion beam microscopy. Beyond ions and single atoms, these s…
Local interface effects modulate global charge order and optical properties of 1T-TaS/1H-WSe heterostructures
Samra HusremoviÄ, Valerie S. McGraw, Medha Dandu +14
1T-TaS is a layered charge density wave (CDW) crystal exhibiting sharp phase transitions and associated resistance changes. These resistance steps could be exploited for inform…
