Representative: Petra Swiderek

Content

Relevance of nanoscopic molecular layers (areas of application, recent examples)
Preparation of monomolecular layers (self-assembly, PVD, growth modes and their kinetics, epitaxy, Langmuir-Blodgett-layers, SAMs)
Methods for investigating the structure of nanoscopic molecular layers (overview, contact angle, ellipsometry, diffraction, optical spectroscopy, electron spectroscopy, scanning probe techniques)
Surface modification and structuring (silicon surfaces as selected example, processes for surface structuring)

Electron-induced elementary processes (mechanisms of electron-molecule interactions, excitation, electron attachment, ionisation, subsequent reactions, kinetics of processes)
Experiments on electron-induced processes (vacuum, surface analytical techniques: TDS, RAIRS, ESD, HREELS, XPS)
Relevance of electron-induced reactions (technical applications of keV- and MeV-electrons, Irradiation with low-energy electrons, plasmas, lithography, radiation damage, atmospheric and cosmic chemistry)
Modification of surfaces by electrons (technical processes, selected examples)
