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
  • Basic physical and chemical deposition methods: MBE, thermal deposition, vapor-phase deposition, magnetron sputtering. Models of growth: Edwards-Wilkinson equation, equation Khardar-Parisi-Zhang, fractal models, scaling relations, growth exponents. Growth modes: Vollmer-Weber, Stranski-Krastanow, van der Merwe. Equilibrium and non-equilibrium plastic relaxation, misfit dislocations. Self-organized quantum dots.
  • III. Surface electron states
  • Free electrons in a potential well, Friedel oscillations. Schroedinger equation of a semiinfinite one-dimensional chain. Condition of the existence of surface states. Charge of surface states and sub-surface layers. Depleted, enriched and inversion layers. Schroedinger equation of a triangular quantum well, model of two-dimensional electron gas. Electron emission from surfaces. Photoelectron spectroscopy (XPS, UPS, ARPES), STM spectroscopy, resonant tunneling.
  • IV. Surface phonon states
  • Conditions of extistence of phonon states localized at surface. Equation of motion of a semiinfinite linear chain. Long-wave limit, Rayleigh waves. Electromangetic wave localized at an interface, surface plasmons and polaritons. High-resolution EELS, methods TERS a SERS
