SS 2016 - Condensed Matter II: Interfaces and Nanostructures

Lecturer: Professor Günter Reitert0.1.jpg
Time:
  (4 hrs per week) Thu 8:15-10:00, Fri 8:15-10:00
Place: HS I, physics highrise
Practicals and experiments: Thu 17:00-18:30

Preliminary Program:
(The course will be given in English)

Motto: "God made solids, but surfaces were the
work of the devil."
Wolfgang Pauli (1900-1958)


 

Goal:
The students should get an overview over phenomena which only appear on surfaces and interfaces (e.g. how to make water running uphill?). The course deals with special structural and electronic properties of liquid and solid surfaces as well as their relevance in many fields of modern material science and nanotechnology.

Content:
Surfaces between solids and liquids can be found in most of the physical, chemical, biological and geological systems, as well as in many technological processes. Although the number of atoms or molecules at these surfaces is comparatively small, this "minority" can often dominate or even control the behavior of large (macroscopic) systems.

Topics:
1.    General description of interfaces: Thermodynamics and kinetics
2.    Interaction forces at interfaces: Short- and long range forces , ...
3.    Liquids and liquid interfaces: Droplets, bubbles, waves, "liquid beads"
4.    Solid-liquid interfaces: Hydrodynamics, capillarity, wetting,...
5.    Structure of solid surfaces: Electronic processes at surfaces
6.    Surface processes: Adsorption/desorption, phase transitions
7.    Making of well defined solid surfaces: Surface reconstruction, surface transport,...
8.    Growth- and decay: Epitaxy, nucleation, lattice mismatches, mechanical stress
9.    Organic layers and nanostructures on surfaces: Directed stucturing of surfaces at nm-scale
