This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.


A dislocation can be observed in TEM because the lattice near the dislocation core is bent elastically. The degree of bending increases when closer to the dislocation core. Dark-field imaging mode, also called weak-beam (WB) technique here, is normally used for dislocation imaging.
