Learning outcome

Students should gain basic knowledge of solid state physics - crystal structures, diffraction and reciprocal lattice, bonding in crystals, phonons and thermal properties of materials, free electron model, energy bands and semiconductors.
This means that the students should
- know and recognize the different crystal structures and understand basic crystallography
- know how we study crystalline materials with diffraction, know what Brillouin zones, Ewald sphere and scattering amplitudes are
- learn what a reciprocal lattice is and how we use it
- know about different types of bonding in materials
- know what phonons are and be able to find dispersion relations for one-dimensional lattices
- learn about heat capacity and the different thermal properties related to phonons
- learn about the free electron model
- understand weak periodic potentials and the introduction of Bloch functions
- understand energy bands, energy gaps and semiconductors, learn about pn-junctions and principles of semiconductor technology
- know what a Fermi surface is, and principles of how to find such.

Learning methods and activities

Lectures, home work problems and mandatory laboratory exercises. A re-sit examination may be changed from written to oral.
