Forward and Reverse Bias PN Junction

Welcome back to KK Awasthi EduHub! In today's session, we are diving deep into one of the most fundamental topics of Semiconductor Physics: the biasing of a PN Junction. Whether you are preparing for your B.Tech (AKTU Syllabus) exams or clearing your basics for competitive entrance tests, this video will help you visualize exactly what happens at the atomic level when we apply external voltage to a diode. 📘 What We Cover in This Video: The Concept of Biasing: Why do we need an external battery for a PN junction? Forward Bias Explained: * Connecting P-type to Positive and N-type to Negative. How the depletion layer width decreases. The movement of majority carriers (holes and electrons) across the junction. Reverse Bias Explained: Connecting P-type to Negative and N-type to Positive. Why the depletion layer widens and prevents current flow. Understanding Minority Carrier movement and Leakage Current. V-I Characteristics: A step-by-step breakdown of the graph for both biasing conditions, including the Knee Voltage and Breakdown Voltage. 🚀 Join the KK Awasthi EduHub Community: If you found this lecture helpful, please Like the video and Subscribe to the channel for more simplified Physics and Engineering tutorials.
