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.
