Lecture
This lecture covers the fundamentals of semiconductor physics, focusing on the behavior of transistors and diodes. It explains the operation of p-n junctions, the characteristics of different types of semiconductors, and the principles behind the functioning of transistors and diodes. The lecture also delves into the concepts of charge carriers, band gaps, impurities, and the generation of light in LEDs. Additionally, it discusses the importance of direct and indirect gap semiconductors, the role of impurities in conductivity, and the behavior of charge carriers under applied potentials.
