From: Fabrication of Subnanometer-Precision Nanopores in Hexagonal Boron Nitride
(a) Hexagonal h-BN pore created by condensing the beam at higher spot sizes to achieve higher current density. (b) Alternating boron and nitrogen facets as demonstrated in ref.45. Boron and Nitrogen represented in gold and blue respectively. The nitrogen terminated facets that normally form the edges of a triangular nanopore are circled in red and are stable at low beam currents while the boron terminated edges are not.
