che411 - Physical Chemistry of Surfaces and Interfaces (Complete module description)

BSc in Chemie, Umweltwissenschaften oder Physik

Students familiarize themselves with complex research-related general concepts of interfacial and surface chemistry, their application in specialized experimental techniques as well as selected examples of their technical application with an emphasis on nanoscale systems.

Master of Science
On the basis of the general knowledge from the BSc. course (chemical thermodynamics, chemical kinetics, electrochemistry, basics of spectroscopy), students select 3 advanced lectures from the catalogue of physical chemistry. According to the research focus on interfacial chemistry, this subject should be represented by a minimum of 2 lectures.

PhD program Interface Science
Students select 1 to 3 lectures (3 KP each) according to interest and need and attend a colloquium (30 min pass/fail) at the end of the semester. PhD students can only select lectures that have not been part of their MSc. curriculum.

These lectures are:
Lecture - Structure of Interfaces and their Characterization, WiSe, freitags 8:30-10:00 Uhr

Thermodynamics of interfaces and adsorption, surface tension, contact angle, wetting, control of wetting, excess quantities, adsorption isotherms, charges at interfaces, transport phenomena at interfaces, colloids, control of interfacial properties in technical processes, interfaces in the environment.
atomic structure of surfaces (two-dimensional lattices, relaxation, reconstruction, notation of surfaces), vibration at surfaces, electronic structure of surfaces
Experimental methods: LEED (principles of diffraction, reciprocal lattices, Brillouin zones), scanning probe techniques (real lattices, tunneling process, STM, AFM) Photoelectron spectroscopy (UPS, XPS), vibrational spectroscopy at surfaces
