Summary

Lectures on the fundamental aspects of semiconductor physics and the main properties of the p-n junction that is at the heart of devices like LEDs & laser diodes. The last part deals with light-matter interaction phenomena in bulk semiconductors such as absorption, spontaneous & stimulated emission.

Content

1. Electronic properties of semiconductors

- Crystalline structures and energy band diagrams

- Impurities and doping

- Carrier statistics in equilibrium and out-of-equilibrium

- Electron transport in weak and strong fields

- Generation and recombination processes

2. Theory of junctions and interfaces

- p-n and metal-semiconductor junctions

- Heterojunction interfaces

3. Light-matter interaction in semiconductors

- Fermi's golden rule, absorption, optical susceptibility, Bernard-Duraffourg condition

- Spontaneous and stimulated emission of radiation

- Dielectric function, optical constants

- Radiative lifetime, photoluminescence spectra
