2. Surface Structure
After studying this section of the module you should:
- understand what is meant by surface free energy;
- understand what is meant by surface reconstruction & relaxation;
- understand and be able to use Wood's notation and matrix notation for surface reconstructions;
- understand the relationship between real space and reciprocal space 2D lattices and how the reciprocal lattice relates to low energy electron diffraction (LEED) at surfaces;
- apply your understanding of real and reciprocal space lattices to the analysis of LEED patterns;
