Course objectives
At the end of the course, students will have the knowledge of the theoretical background used in quantum-mechanical calculations of solids and in computational thermodynamics (CALPHAD method). They will understand the rules of working with particular programs. Acquired theoretical knowledge will be used in the practical part of the course. Students will be able to perform basic calculations and present the obtained results.
Syllabus
  • 1. Introduction: Principles of modeling. Role of modeling in contemporary solid state chemistry and materials science. Relation between experimental and theoretical description of phases. 2. Crystallography: crystal structure of material and its description, symmetry, relations between crystal structure and thermodynamics, ordering, types of phases. 3. Basic concepts of quantum chemistry (wave functions, probability density, Schrödinger equation). Description of solids from first principles (Born-Oppenheimer approximation, density functional theory, exchange and correlation energy functional, Bloch theorem). Methods of electronic structure calculations (APW, OPW, LCAO, KKR, LMTO, LAPW, pseudopotentials). 4. Introduction to Linux and to supporting programs (SSH, vi editor, ...) used in quantum-mechanical calculations in this environment. 5. Quantum-mechanical calculations I (parameters affecting the accuracy of calculation - suitability of method, k-points mesh, cutt-off energy). Practical application of acquired knowledge (input files and calculation). 6. Quantum-mechanical calculations II (pure element in basic state: energy, structural and mechanical properties, band structure, density of states, magnetism). Practical application of acquired knowledge (output files and processing of results). 7. Quantum-mechanical calculations III (modeling of theoretical strength, displacive phase transformations, energies of formation, polymorphism. Lattice defects. Diffusion barriers, surfaces, interfaces, composites). Practical application of acquired knowledge. 8. Basic concepts of computational thermodynamics (laws of thermodynamics, equilibrium, CALPHAD method, phase diagrams). 9. Models of phases and their relationship to structure, Gibbs energy of phase and its dependence on temperature, pressure and composition. 10. Calculations of phase equilibria by CALPHAD method I (input data for semi-empirical modeling, thermodynamic databases). Practical application of acquired knowledge (input files). 11. Calculations of phase equilibria by CALPHAD method II (search for thermodynamic equilibrium, Gibbs energy minimization). Practical application of acquired knowledge (calculation of phase diagram). 12. Calculations of phase equilibria by CALPHAD method III (thermodynamic assessment, optimization of thermodynamic data). Practical application of acquired knowledge (optimization and calculation of phase diagram). 13. Presentation of results, discussion of methods used and approaches.
