Polar Topologies in a Ferroelastic Metal Membrane
Rahil Haria, Noah Schnitzer, T. Ben Britton +10
Polar metals, materials in which electric polarisation and metallicity coexist, are exceptionally rare because itinerant electrons screen long-range dipoles and favour centrosymmet…
Helium-Cooled Cryogenic STEM Imaging and Ptychography for Atomic-Scale Study of Low-Temperature Phases
Noah Schnitzer, Mariana Palos, Geri Topore +7
Much of the exotic functionality of prime interest in quantum materials emerges from structural and electronic ground states that can only be accessed at cryogenic temperatures. Un…
Quantifying Phase Transformations in Alloying Anodes via In-Situ Liquid Cell Hard X-ray Spectroscopy and Cryogenic Microscopy
Neil Mulcahy, Syeda Ramin Jannat, Yaqi Li +7
Understanding electrochemical phenomena at complex liquid solid interfaces requires linking real time structural dynamics with atomic scale interfacial chemistry. Here, we integrat…
Polarization Domain Mapping From 4D-STEM Using Deep Learning
Fintan G. Hardy, Sinead M. Griffin, Mariana Palos +4
Polarization in ferroelectric domains arises from atomic-scale structural variations that govern macroscopic functionalities. The interfaces between these domains known as domain w…
Programmable Beam Control for Electron Energy-Loss Spectroscopy and Ptychography
Mariana Palos, Liam Spillane, Geri Topore +5
Programmable electron-beam scanning offers new opportunities to improve dose efficiency and suppress scan-induced artifacts in scanning transmission electron microscopy. Here, we s…
