Infrared surface and interface studies - vibrational analysis and beyond — •Annemarie Pucci — Kirchhoff-Institut für Physik der Universität Heidelberg

Various excitations can be studied in the infrared, vibrational spectra, low-energetic electron transitions, and plasmonic behaviour. With careful referencing, such excitations can be observed also on surfaces and in ultrathin layers. The excitation spectra deliver information on the atomic level and, furthermore, on collective behaviour. In the talk examples for ultra-high vacuum studies will be presented, for example, charge transfer at organic-inorganic interfaces and plasmonic excitations in low-dimensional systems.
