Aims
On completion of this TLP you should be able to:
- explain to someone with A-level physics how a TEM works and how it forms a) an image and b) a diffraction pattern;
- name the essential components of a TEM and define the meaning and significance of important terms such as resolution, magnification, image contrast...
- explain the operation of electromagnetic lenses in terms of ray diagrams, particularly in the illumination system and the objective/intermediate system;
- explain to a materials undergraduate how different types of contrast arise from beam-specimen interactions, and how these can be used to study materials in the TEM.
