Principles of Semiconductors and Magnetism

Semiconductors and magnetism form the backbone of modern technology, powering everything from computing hardware to advanced sensing equipment. This course provides a rigorous, foundational understanding of the physics behind these essential topics, enabling you to confidently analyze electronic circuits and understand magnetic phenomena. This course will transform your theoretical understanding into practical knowledge: * Understand the energy band theory, doping, and charge carrier behavior in intrinsic and extrinsic semiconductors. * Analyze the operation and characteristics of fundamental solid-state devices, including p-n junction diodes and basic transistor structures. * Learn the principles of electromagnetism, including magnetic fields, magnetic materials (dia, para, ferro), and electromagnetic induction. * Apply concepts of hysteresis and magnetic domain theory to understand modern magnetic storage and sensing technologies. * Practice solving problems related to rectification, filtering, and magnetic force calculations. We begin by defining key terminology and the quantum basis of solid-state materials before moving into detailed analysis of semiconductor physics and device operation. The second half focuses on core magnetic principles, material properties, and their real-world applications. This course is designed for absolute beginners, including aspiring physics students, electrical engineering entrants, and hobbyists with no prior knowledge of solid-state physics or advanced electromagnetism.
