Quantification of the Information Limit of Transmission Electron Microscopes [PDF]

open access: yesPhysical Review Letters, 2008
The resolving power of high-resolution transmission electron microscopes is characterized by the information limit, which reflects the size of the smallest object detail observable with a particular instrument. We introduce a highly accurate measurement method for the information limit, which is suitable for modern aberration-corrected electron ...
