Lecture
This lecture covers recombination processes in semiconductors, including radiative recombination, Auger recombination, and Shockley-Read-Hall recombination. It explains the mechanisms of generation and recombination of electron-hole pairs, the impact of doping levels on recombination rates, and the role of defect states in recombination. The lecture also discusses the importance of different recombination processes in various semiconductor materials, such as silicon and GaAs, and provides examples of recombination scenarios in solar cell materials.
