05-MCM-1-P4 Chemistry

Representative: Marcus Bäumer


The module will cover the following topics:
1. Thermodynamic basics of surfaces
(surface energies, curved surfaces (Kelvin equation, partial pressure of liquid droplets), wetting and contact angle (Young equ.))
2. Geometric structure
(crystallographic orientation of surfaces, description of superstructures, reconstruction, relaxation)
3. Diffraction at surfaces: LEED, RHEED
4. Adsorption at surfaces
(physisorption, chemisorption, Langmuir isotherm, BET, temperature programmed desorption)
5. Probing surfaces with electrons
(Diffraction, spectroscopy with electrons, electron-induced reactions)
- solid state physics
6. Description of crystalline solids
7. Methods used in solid state material science
8. Classes of compounds and materials
9. Electronic structure (band structure, Bloch waves, metals and insulators, photoelectron spectroscopy (ARUPS))
10. Lattice vibrations (basic modes, phonons, dispersion, specific heat, anharmonic effects (thermal expansion, thermal conductivity))
11. Metals and Semiconductors (electrical conductance, thermodynamics of the electronic system, intrinsic semiconductors, dopants, p-n junction, photodiode and solar cell)
12. Magnetism (basic modes, domain walls, hysteresis, superconductivity)

Learning Outcome

After attending the module, the students will have an overview over concepts in solid state and surface chemistry and physics. They will be able to apply these concepts to describe the structural and electronic properties of metals, semiconductors and insulators. In addition they will have a basic knowledge about synthesis of solid materials.
The participants will
- know the special thermodynamic features of surfaces and apply the corresponding concepts and equations
- predict the atomic arrangement of differently oriented surfaces based on basic structural data and information on relaxation and reconstruction
- predict the diffraction pattern of differently oriented surfaces and know advanced options to use LEED and RHEED for the determination of surface structures
- judge the relevance of electrons to study surfaces, be able to enumerate the different experimental possibilities to probe structure and composition, and differentiate between several mechanisms of electron-induced surface reactions
- know and properly use basic terminology of solid state physics and understand its meaning
- know and differentiate between basic experimental methods to analyze the electronic and vibrational structure of solids
- interpret depictions of electronic and vibrational band structure
- predict magnetic, electrical, and thermal properties of metals, insulators and semiconductors based on basic structural data
