Surface Physics

Instruction is in the form of lectures, seminars, and mandatory laboratory assignments. Course content: <br> \- Introduction to vacuum technology. <br> \- The atomic structure of surfaces. Reconstruction and relaxation. Structural research methods, especially electron diffraction. Preparation of surfaces, growth of ultra-thin films. <br> \- The electronic structure of surfaces. Spectroscopic research methods, especially photoemission, theory of angle-resolved photoemission. Surface band structure and surface states of various metal- and semiconductor surfaces. <br> \- Band bending and Fermi-level pinning of semiconductor surfaces. Metal-semiconductor interfaces, semiconductor heterostructures, the Schottky barrier. Introduction to collective phenomena on surfaces and in interfaces, especially superconductivity and ferromagnetism.<br> \- Adsorption and chemical reactions on surfaces.
