Topological vectors as a fingerprinting system for 2D-material flake distributions

Abstract The production of 2D material flakes in large quantities is a rapidly evolving field and a cornerstone for their industrial applicability. Although flake production has advanced in a fast pace, its statistical characterization is somewhat slower, with few examples in the literature which ma...
