Course objectives
The lecture deals withthe basic concepts of the theory and calculations of electronic structure of solids. Firs, the basic principles and relations are presented. Subsequently, modern methods of electronic structure calculations are outlined and their applications are shown, including magnetism, structural stability, maechanical properties, phase diagrams and multiscale modelling of atomic configuration of extended defects. The concluding part of the lecture is devoted to nanostructure materials.
Syllabus
  • Basic concepts of quantum physics and chemistry: the wave function, probability density, Schrödinger equation, the analysis of simple quantum systems. Fundamentals of ab initio approach to the electronic structure of solids: Schrödinger equation for a solid, Born-Oppenheimer approximation, density functional theory, exchange-correlation energy functional, its local approximations. Principles of methods for electronic structure calculations and their survey (APW, OPW, LCAO, KKR, LMTO, LAPW, pseudopotentials, KKR). Bloch theorem, tight-binding approximation. The role of Green functions in solid-state theory, expression for the local density of states and of the charge density by means of Green functions. Practical illustration of electronic structure calculations for transition metals by the LMTO method the band structure, density of states, total energy, higher-energy structures, polymorfism. Electronic structure calculations for disordered alloys: coherent potential approximation, examples of results for cubic and hexagonal alloys. Electronic structure calculations for surfaces and interfaces: principal layer, surface Green function, examples of results for surfaces and grain boundaries in transition metals. Magnetism in solids: its origin, the description of electronic states, Heisenberg and Stoner model of magnetism. Basic types of magnetic behavior (dia-, para-, fero- and antiferomagnetism). Magnetic properties of metallic multilayers: basic properties and application of metallic multilayers, magnetic anisotropy, interlayer exchange coupling, giant magnetoresistence. The importance of total energy for investigation of stability and mechanical properties of materials, the existence of higher-energy structures and polymorfism, modeling of atomic configuration of extended defects, theoretical strength of materials. Multiscale modeling: from electron and atomistic dimension over the mesoscopic level to the continuum mechanics. Example: brittle fracture and propagation of cracks. Application of ab initio electronic structure calculations in construction of phase diagrams of metallic systems, the CALPHAD approach. Electronic structure and atomic configuration of nanocrystalline materials. Example of the structure of nanocrystalline nickel. The role of ab initio electronic structure calculations in contemporary solid-state physics and chemistry and in materials science.
