In this lecture, we explain the formation of the PN junction, diffusion and drift currents, depletion region, barrier potential, equilibrium condition, and diode behavior without external voltage. You will also understand how the diode works under forward bias and reverse bias, including potential barrier changes, current flow, and carrier movement. The lecture is simple, diagram-based, and exam-focused, making it ideal for theory and viva questions. This lecture is useful for RGPV BTech 1st Year students and aligns with syllabi of AKTU, VTU, GTU, JNTU, SPPU, and other engineering universities. 📘 This Semiconductor Physics Playlist Includes: Introduction to Semiconductors Intrinsic & Extrinsic Semiconductors PN Junction Diode Forward & Reverse Bias Avalanche Breakdown Zener Diode Tunnel Diode Photo Diode & Solar Cell 🎯 This Video Is Helpful For: BTech 1st Year (RGPV) – All Branches Semiconductor Physics Unit Students preparing for university exams Students needing clarity in PN junction formation GATE / NET / IIT-JAM electronics basics PN Junction Diode is a core exam topic, frequently asked in long-answer questions with diagrams. 🏷️ Keywords : pn junction diode pn junction formation depletion region barrier potential diffusion current drift current forward bias reverse bias semiconductor diode engineering physics semiconductor btech 1st year physics energy band diagram pn junction carrier movement in diode rgpv engineering physics semiconductor device basics engineering physics btech engineering physics exam preparation education point online sachin sir engineering physics sachin bhardwaaj engineering physics 🔖 Hashtags #EngineeringPhysics #Semiconductors #PNJunction #Diode #BTech1stYear #RGPV #SachinSir #BTechJunction
