Description

"Semiconductor Physics: Foundations, Devices and Technology" presents a clear, comprehensive, and application-oriented exploration of the science that powers today's electronic and optoelectronic world. Blending fundamental concepts with modern technological perspectives, this book provides a strong foundation for students, researchers, and professionals in physics, materials science, electronics, and nanotechnology. The book begins with essential semiconductor principles, including crystal structures, energy band theory, intrinsic and extrinsic behavior, doping mechanisms, and charge carrier dynamics. Topics such as carrier generation, recombination, mobility, diffusion, and Fermi-Dirac statistics help readers understand semiconductor behavior under various physical and electrical conditions. Progressing from theory to devices, the text explains the physics and operation of p-n junctions, diodes, BJTs, FETs, MOS capacitors, MOSFETs, LEDs, photodiodes, solar cells, and laser diodes. Each device is introduced through its working principle, electrical characteristics, performance parameters, and practical applications in circuits, communication systems, and power electronics. A significant strength of the book is its coverage of fabrication and material technologies. Crystal growth, epitaxy, lithography, etching, oxidation, diffusion, thin-film deposition, and cleanroom processing are discussed alongside major characterization tools such as XRD, SEM, TEM, AFM, Raman spectroscopy, photoluminescence, Hall measurements, and electrical testing. The closing chapters highlight advanced and emerging semiconductor materials-SiC, GaN, graphene, MoS₂, organics, perovskites, and nanoscale structures and their roles in high-frequency devices, power electronics, flexible systems, and next-generation photonics. Written in an accessible and structured style, this book serves as a unified resource that connects fundamental semiconductor physics with real technological application.
