- Syllabus
- I. Surface crystallography
- Surface energy vs. surface tension. Crystal shapes, Wulff construction. Two-dimensional lattices, point groups, Bravais lattices Two-dimensional Brillouin zones. Real surfaces, singular and vicinal surfaces. Surface relaxation and reconstruction. Adsorption and desorption from surfaces, passivation, oxidation. The LEED method, surface x-ray scattering (XRR,SXRD).
- II. Growth of epitaxial layers
