Three-Dimensional Sectioning of Specimens using STEM
- Practical Electron Microscopy and Database -
- An Online Book -  

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


Spherical-aberration (Cs) correction results in a reduced depth of focus (DoF) with the increase in the convergence angle θ, therefore, the three-dimensional (3-D) sectioning of the samples using STEM [1,2] can be improved. However, the achievable vertical information in real systems would also depend on many sample-related factors, for instance, channelling effect.
