Textbook in PDF format A profound knowledge about crystal growth fundamentals and processes is needed for nanocrystals, epitaxial thin films and bulk crystals which became significant as the centerpieces of micro- and optoelectronics, photonics, computing. The mastery of crystallization and epitaxial processes requires a profound interdisciplinary knowledge that combines chemistry, crystallography, material science, physics. This three-volume textbook presents the three pillars of experimental crystal growth: Thermodynamics of crystallization. Kinetics of crystallization. Transport of heat and mass. Part 1: Thermodynamics of Crystallization. Lectures by the experienced teacher: Highly didactical approach. Coloured boxes with highlighted equations. Step-by-step explanations. Introduction The potential of Gibbs Phase equilibrium and phase diagrams Surfaces, phase boundaries, and interfacial effects Deviation from equilibrium Conclusions
