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…
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…
Navigating Chiral Spin Architectures in Non-Collinear Antiferromagnetic Thin Films
Freya Johnson, Jan Zemen, Geri Topore +6
Noncollinear antiferromagnets offer much promise for antiferromagnetic spintronics and neuromorphic applications with a plethora of functional properties surpassing many competing…
Degradation and SEI Evolution in Alloy Anodes Revealed by Correlative Liquid-Cell Electrochemistry and Cryogenic Microscopy
Neil Mulcahy, Syeda Ramin Jannat, Geri Topore +5
Understanding solid liquid interfaces at high spatial and chemical resolution is crucial for advancing electrochemical energy storage technologies, yet this remains a persistent ch…
