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…
Observation of spin-valley locked nodal lines in a quasi-2D altermagnet
Quanxin Hu, Xingkai Cheng, Qingchen Duan +19
The interplay among quantum degrees of freedom-spin, orbital and momentum-has emerged as a fertile ground for realizing magnetic quantum states with transformative potential for el…
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…
