Introduction to Electrons in Crystals (4 Parts)

Synopsis

1: Terminology, with 100 electron-related terms in the MATTER glossary. Covers auger transitions,and characteristic X-ray emission, selection rules.
2: Introduces the interaction of high-energy electrons with atoms of aluminium ast the example. Also considers plasmon, phonon, inner-shell and valence electron excitations; subsequent relaxation to give Auger electrons; characteristic X-rays. Intended to support the teaching of physical techniques such as electron microscopy and spectroscopy.
3: Introduces fundamental concepts of population inversion, pumping and confinement; illustrates stimulated emission and systems with two and three states together with the use of a biased p-n junction to obtain population inversion. Also an animation of a semiconductor heterojunction laser.
4: Develops quantitatively the ideal parabolic N(E) curve; introduces quantitavely the importance of diffraction in creating band gaps and zone boundaries. Illustrates the non-ideally free-electron nature of real materials using a few selected band diagrams and DOS curves.
