“Resolution” in high-resolution electron microscopy [PDF]

open access: yesUltramicroscopy, 1992
Abstract In the field of high-resolution transmission electron microscopy (HRTEM), the term “resolution” has come to hold a number of different meanings [M.A. O'Keefe and J.C.H. Spence, in: Proc. 49th Annual EMSA Meeting, p. 498]. The present work reviews the various definitions of HRTEM resolution, derives theoretical expressions for resolution, and
