L1: Semiconductor Physics of Diode | Analog Electronics | GATE/ESE 2022 | Ashu Sir

In this video, Ashu Sir has detailed the background physics involved in the functioning of diode. Types of semiconductors are elaborated with the band theory. Mathematical expressions of drift current and diode current are derived from the scratch. Einsteins relation is derived at the end of the lecture.

Watch the video till the end to know more about the Semiconductor Physics of Diode. This will help you to cover the full syllabus of Analog Electronics for GATE & ESE 2022 - EE, ECE, IN. Feel free to ask your all queries and get the answers shortly. So, let's start the journey.
