Solid-state nanopores offer advantages in stability and tunability, but a scalable method for creating nanometer-thin solid-state pores has yet to be demonstrated. Here we demonstrate that solid-state nanopores with nanometer-thin constrictions can be produced by “cold ion beam sculpting,” an original method that is broadly applicable to many materials, is easily scalable, and requires only modest instrumentation.en-USnanoporous materialsion beamssputteringtransmission electron microscopyfocused ion beam technologyJournal Article2016-09-1310.1063/1.4719679
