Semiconductor Fundamentals: Physics and Devices

Semiconductors are the building blocks of all modern electronics, from smartphones to supercomputers. Understanding how they work is essential for anyone interested in electrical engineering, physics, or materials science. This course provides a solid theoretical foundation in semiconductor physics, enabling you to clearly grasp the function and design of diodes, transistors, and integrated circuits. What you'll learn: * Understand the fundamental band theory that classifies materials as conductors, insulators, or semiconductors. * Master the process of doping and how it creates P-type and N-type materials used in junctions. * Learn the detailed operation and characteristics of the PN junction diode and its applications in rectification. * Analyze the structure and working principles of Bipolar Junction Transistors (BJTs) and Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs). * Apply foundational device physics concepts to understand the principles governing modern CMOS scaling and integrated circuit design. We begin by defining key terminology and the quantum mechanics necessary to describe electron behavior in solids. The course then systematically covers material properties, junction formation, and the operational characteristics of fundamental semiconductor devices. This text-only course is designed for absolute beginners with no prior experience in solid-state physics or electronics. No prerequisites are required.
