The course is meant to present the main physico-chemical notions as relevant to the technology of avanced materials
Triennial degree in physics and/or triennial degree in science and tecnology of materials
Course contents summary
Reminds of phenomenological thermodynamics: equilibrium conditions of
multiphase systems, multiple equilibria, estimates of thermodynamic
quantities. First-order phase transitions and their driving forces.
Homogeneous and heterogeneous nucleation: thermodynamic (capillary theory)
and kinetic aspects.
Elements of fluid dynamics: mass, heat and momentum transport equations;
two-phase system transitions and the general Stefan problem. Approximate
solutions of the Stefan problems. Stagnant boundary layer theory.
Coupled fluid dynamic and kinetic aspects in first-order phase
transitions. Various applications to the growth technology of crystalline
The stability conditions of growing crystal interfaces: constitutional
supercooling and brief account of Mullin-Sekerka morphological stability
theory. Compositional stability in growing crystals: impurity/dopant
concentration profiles; isotropic and anisotropic segregation at macro-
and micriscopic level. Solid-state diffusion. Main growth techniques of
bulk crystals (melt, solution and vapour growth).
