Crystals grown by molecular beam epitaxy (MBE) today form the basis for the most advanced device structures in solid-state physics, electronics and optoelectronics. "Materials Fundamentals of Molecular Beam Epitaxy" gathers together the basic principles that apply to MBE and treats its most important aspects in great depth. The book begins with the basic concepts underlying solid state physics and materials science and ends at the frontiers of modern research. Throughout, it teaches the usefulness of thermodynamic and statistical calculations based on intuititive and physically motivated semi-empirical models. "Materials Fundamentals of Molecular Beam Epitaxy" is thorough enough to benefit graduate students and professional researchers, yet it is also broad enough to benefit materials, surface, and device researchers interested in gaining a deeper appreciation of the modern science of epitaxy.
