Learning outcomes

The course will prepare for fundamental and applied research within surface physics and related fields, such as material science, material chemistry and nanoscience.

After completing the course the student should be able to:

• describe the atomic structure of crystalline low-index surfaces, and using simple models calculate surface energies for simple surfaces and show the connection between the surface energy and the shape of particles and reconstructions of surfaces,
• use the connection between real space and reciprocal space to show how this gives rise to diffraction patterns and master the different notations used to assign overlayers and reconstructions,
• describe the principles behind the most important spectroscopic and microscopic methods used in surface science, which information that is attained from these techniques and how various methods can be combined,
• explain the characteristics for different kinds of adsorption with respect to binding energy, binding distance, surface coordination and electronic structure,
• derive and apply basic kinetic models for the processes of adsorption and diffusion,
• describe fundamental catalytic reactions, derive simple kinetic models that describe these reactions and show how one can diagnose the reaction,
• describe different ways to grow films and how the growth mode is connected to the surface energy of the materials.
