Quantitative Electron Beam-Single Atom Interactions Enabled by Sub-20-pm Precision Targeting.

ABSTRACT: The ability to probe and control matter at the picometer scale is essential for advancing quantum and energy technologies. Scanning transmission electron microscopy offers powerful capabilities for materials analysis and modification, but sample damage, drift, and scan distortions hinder single atom analysis and deterministic manipulation. Materials analysis and modification via electron-solid interactions can be transformed by precise delivery of electrons to a specified atomic location, maintaining the beam position despite drift, and minimizing collateral dose. Here a fast, low-dose, sub-20-pm precision electron beam positioning technique is developed, "atomic lock-on," (ALO), which offers the ability to position the beam on a specific atomic column without previously irradiating that c
