Published in Carbon: "Characterization of hydrogen plasma defined graphene edges"

Our international team characterizes the quality of remote hydrogen plasma defined graphene edges by Raman spectroscopy, atomic resolution AFM and low temperature electronic transport measurements. For graphene on hBN, the edge is ~40% zigzag and ~60% armchair-30 degree segments, while overall running in the zigzag direction. Rehmann, Kalyoncu et al., Carbon 150, 417 (May 24, 2019).
