Fabrication and characterization of boron-terminated tetravacancies in monolayer hBN using STEM, EELS and electron ptychography
Dana O. Byrne, Stephanie M. Ribet, Demie Kepaptsoglou +3
Tetravacancies in monolayer hexagonal boron nitride (hBN) with consistent edge termination (boron or nitrogen) form triangular nanopores with electrostatic potentials that can be l…
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…
Atomic Engineering of Triangular Nanopores in Monolayer hBN: A Decoupled Seeding and Growth Approach
Dana O. Byrne, Frances I. Allen
Nanopores in 2D materials are of significant interest in advanced membrane technologies aimed at the sensing and separation of ions and molecules. These applications necessitate 2D…
Probing defectivity beneath the hydrocarbon blanket in 2D hBN using TEM-EELS
Dana O. Byrne, Jim Ciston, Frances I. Allen
The controlled creation and manipulation of defects in 2D materials has become increasingly popular as a means to design and tune new material functionalities. However, defect char…
Iterative Phase Retrieval Algorithms for Scanning Transmission Electron Microscopy
Georgios Varnavides, Stephanie M. Ribet, Steven E. Zeltmann +7
Scanning transmission electron microscopy (STEM) has been extensively used for imaging complex materials down to atomic resolution. The most commonly employed STEM modality, annula…
