Lay Summary (English)

Lead
Lay summary
Molecular monolayers at surfaces and interfaces provide interesting and technologically relevant materials system to be investigated. Novel effects consist in the multi phase adsorption and layering by self organisation (structure), the induced magnetic ordering (chemical and magnetic coupling) and the electronic coupling on conductive and insulating interfaces. The delicacy of these materials, particularly in surface preparations of about monolayer thickness requires electron spectroscopic measurements and scanning probe microscopic investigations at the least interacting conditions. Therefore two instrumental upgrades are requested: An X-ray monochromator for higher resolution photoelectron spectroscopy as well as a new data acquisition and control unit for low current Scanning Tunneling Microscopy and Spectroscopy. By using this equipment, PhD students at the Paul Scherrer Institute (PSI) can uniquely prepare for highly sophisticated surface science experiments at three surface science beamlines of the Swiss Light Source (SLS) and approach a number of scientifically attractive questions with photons, photoelectrons and local probe methods
