Structure and crystallography: Bravais-lattice, unit cells, crystal systems, point groups and space groups. Defects.

Band-theory: Quantum mechanical foundation, Kronig-Penney model, density of states, calculations.

Quasiparticles: excitones, metals and Fermi-gas, semi-conductors, quantum confinement, quasi particles in magnetic fields.

Quantized waves: phonons, coherent states, energy density

Interaction of quasi particles: phonons, photons and/or electrons; thermal and electrical conduction.

Complex susceptibility: dielectric systems, Krames-Kronig relations, polaritones, optics.

Spin and magnetic system: magnetic structures, Ising model, critical fluctuations, domains, spin-waves, spin-spin interactions.

Note that the exam language will be the same as the teaching language.

Learning outcome

After completing the course, the student should:

  • K1 Apply fundamental crystallographic concepts to describe solid state materials
  • K2 Being able to decribe the band-concept and link it to the properties of solid state materials
  • F1 use the quantization-concept to describe transport properties and interactions of quasi-particles.
  • K3 Have obtained insight into dielectric and magnetic systems, and fundamental interactions within these.

Course assessment

There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
