Key Points

  • This research aims to fabricate a freestanding single layer of hexagonal boron nitride and identify its defects.
  • Fabricated a freestanding single layer of h-BN through controlled energetic electron irradiation
  • Utilized layer-by-layer sputtering process for fabrication
  • Resolved atomic defects using aberration corrected high-resolution transmission electron microscopy with exit-wave reconstruction.
  • Identified triangular shaped atomic defects in h-BN
  • Found boron monovacancies to be preferentially formed
  • Proved that the dominating zigzag-type edges are nitrogen terminated.

Abstract

A freestanding single layer of hexagonal boron nitride (h-BN) has been successfully fabricated by controlled energetic electron irradiation through a layer-by-layer sputtering process. We have successfully resolved atomic defects in h-BN with triangle shapes by means of an aberration corrected high-resolution transmission electron microscopy with exit-wave reconstruction. Boron monovacancies are found to be preferably formed and the dominating zigzag-type edges are proved to be nitrogen terminated.
