Description
Jan Vymazal and co-authors studied in 2026 how oxidation spreads from a still microscope tip across stacked graphene sheets. A voltage on an atomic force microscope tip can oxidize graphene locally, a handy way to prototype tiny devices. Earlier work covered single sheets; this team asked how layer count changes the spreading.
Three pattern families appeared as sheets stacked higher. Thin stacks of two to eight layers formed craters, a central pit ringed by a raised rim. Mid stacks etched in a fairly even, round fashion, while a thick twenty-eight-layer stack etched unevenly along preferred directions. Wetter air widened the patterns, but longer tip contact did not clearly matter. Field calculations plus microscopy supported a model where oxidation starts at defects and splits in the sheets. The results guide finer patterning of graphene devices.
