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…
Focused helium ion beam nanofabrication by near-surface swelling
Sherry Mo, Dana O. Byrne, Frances I. Allen
The focused helium ion beam microscope is a versatile imaging and nanofabrication instrument enabling direct-write lithography with sub-10-nm resolution. Subsurface damage and swel…
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…
