Superconducting Niobium Tip Electron Beam Source
Cameron W. Johnson, Andreas K. Schmid, Marian Mankos +7
Modern electron microscopy and spectroscopy is a key technology for studying the structure and composition of quantum and biological materials in fundamental and applied sciences.…
Near-monochromatic tuneable cryogenic niobium electron field emitter
Cameron W. Johnson, Andreas K. Schmid, Marian Mankos +6
Creating, manipulating, and detecting coherent electrons is at the heart of future quantum microscopy and spectroscopy technologies. Leveraging and specifically altering the quantu…
Fast Grain Mapping with Sub-Nanometer Resolution Using 4D-STEM with Grain Classification by Principal Component Analysis and Non-Negative Matrix Factorization
Frances I Allen, Thomas C Pekin, Arun Persaud +5
High-throughput grain mapping with sub-nanometer spatial resolution is demonstrated using scanning nanobeam electron diffraction (also known as 4D scanning transmission electron mi…
Proton Irradiation-Decelerated Intergranular Corrosion of Ni-Cr Alloys in Molten Salt
Weiyue Zhou, Yang Yang, Guiqiu Zheng +4
The effects of ionizing radiation on materials often reduce to "bad news." Radiation damage usually leads to detrimental effects such as embrittlement, accelerated creep, phase ins…
Patterned Probes for High Precision 4D-STEM Bragg Measurements
Steven E Zeltmann, Alexander Müller, Karen C Bustillo +4
Nanoscale strain mapping by four-dimensional scanning transmission electron microscopy (4D-STEM) relies on determining the precise locations of Bragg-scattered electrons in a seque…
Plasmonic lenses for tunable ultrafast electron emitters at the nanoscale
Daniel B. Durham, Fabrizio Riminucci, Filippo Ciabattini +4
Simultaneous spatio-temporal confinement of energetic electron pulses to femtosecond and nanometer scales is a topic of great interest in the scientific community, given the potent…
