Junction Diode: Physical Principles

This lecture covers the physical principles behind the junction diode, starting with Bohr's model of the atom and the energy levels. It explains intrinsic semiconductors, N and P doping, and the formation of the PN junction. The lecture also delves into the conduction mechanisms in intrinsic and doped semiconductors, highlighting the creation of electron-hole pairs. The characteristics of a junction diode, including the current-voltage relationship, are discussed, along with the equations governing diode behavior. Practical aspects such as circuit implementation and characteristic curves are also explored.
