Abstract
A scanning transmission electron microscope for scanning a primary electron beam on a sample, detecting a transmitted electron from the sample by a detector, and forming an image of the transmitted electron. The scanning transmission electron microscope includes an electron-optics system which enables switching back the transmitted electron beam to the optical axis by a predetermined quantity, and a determining unit for determining the quantity based on a displacement of the transmitted electron with respect to the detector caused by the scanning of the primary electron beam.
