The development of nanoelectronics and nanotechnologies has been boosted significantly by the emergence of 2D materials because of their atomic thickness and peculiar properties, and developing a universal, precise patterning technology for single-layer 2D materials is critical for assembling nanodevices.Demonstrated here is a nanomachining sophie allport zebra technique using electrical breakdown by an AFM tip to fabricate nanopores, nanostrips, and other nanostructures on demand.This can be achieved by voltage scanning or applying a constant voltage while moving the tip.

By measuring the electrical current, the formation process on single-layer materials was silver lining herbs kidney support shown quantitatively.The present results provide evidence of successful pattern fabrication on single-layer MoS2, boron nitride, and graphene, although further confirmation is still needed.The proposed method holds promise as a general nanomachining technology for the future.
