The course gives an introduction to quantum physics and quantum mechanics applied to atoms and solid materials, with focus on issues within materials physics that an engineer may encounter.
The course describes:
quantum physics and the particle-wave duality principle, the Schröding equation and its solution for a few selected potentials.
The construction of the atom and the periodic table. The quantum numbers of the electron and the electron spin.
Molecules and chemical bond. Rotations and vibrations.
Materials physics: crystal lattice, X-ray diffrcation, lattice vibrations, the free electron model and the electric and thermal properties of metals. Energy bands, optical and electrical properties of semiconductors, electronic devices.
The main goal of the course is to give an introduction to the microscopic physics that govern the behaviour of electrons, atoms, nuclei and how this relates to macroscopic properties of solid materials.
After the course the student should be able to:
- judge when a classic description is sufficient to solve a problem and when a quantum mechanical description is necessary.
- describe the construction of the atom and the periodic table and what the quantum numbers represent.
- describe and give example of chemical bonds and what effect it has on the electrical, optical and mechanical properties of a solid material.
- describe how and why a nuclear power plant functions
- describe the atomic lattices, their dynamic properties and how structure and lattice parameter are determined by X-ray diffraction
- describe the free electron model, and from this one estimate the thermal and electrical properties of metals.
- describe the influence of a periodic potential on the electrons in a solid material
- determine electrical and optical properties from a band diagram
- describe and calculate electrical properties of some electronic components.
