Description

The course is an introduction to advanced experimental equipment and methods to analyse surfaces of solid materials and soft organic films. Ultra high vacuum techniques are used to study solid state surfaces, reaction of gas phase molecules at surfaces, and new materials which can be created on surfaces, such as thin films for coatings and electronic materials. The instruments used for surface analysis include electron microscopes, electron spectrometers, mass spectrometers, scanning probes (STM, AFM), and equipment for studying low energy electron diffraction. The course will also give an introduction into modern techniques to analyse the formation of thin organic films by self-aggregation, e.g. the formation of mono- and bi-layers of lipid films in contact with water. The techniques presented in this context are X-ray diffraction, neutron reflectometry, Langmuir-Blodgett technology, AFM, and FCS.

Experiments:
1. Electron spectroscopy and microscopy (AES, XPS, SEM+EDX, ELS).
2. Surface structure, morpholgy, and and mechanical state of deposited thin layers on solid and liquid supports (Langmuir compression, reflextometry; LEED, STM, AFM, ELS).
3. Thermodynamic studies of lipid shells: fluid-solid transition, behaviour of mixtures.
