UHV reflection-absorption IR spectroscopy
Electronic & Chemical & Magnetic Characterization (Optical spectroscopy)
(UHV-RAIRS) ultrahigh vacuum reflection-absorption infrared spectroscopy permits vibrational spectroscopic studies at grazing incidence on adsorbed molecules on well-defined solid surfaces.
In UHV-RAIRS, the optical path is entirely evacuated to avoid background signals from gas phase species and results in a superior sensitivity and stability of the system. Essential prerequisites for monitoring molecular species adsorbed, e.g., on oxide single-crystal surfaces are wide pressure (UHV to ambient conditions) and temperature ranges (1000-100 K).

Reflection Absorption Infra-Red Spectroscopy (mid- and near IR) under ultra-high vacuum conditions and at low temperatures (T=15-300K). Complete evacuated optical path to avoid background signals from gas phase species.
Bruker, VERTEX 70V spectrometer.
Mid-IR: standard globar and a water-cooled high-power source. Near-IR: tungsten halogen lamp.
Maximum dimensions: 15 x 15 mm^2. For low temperature experiments: 10 x 10 x 1 mm^2. Substrate needs to be IR reflective (e.g., Au, Al, Cu...).
Base pressure: 4 x 10^-10 mbar. Temperature control: 15 - 300 K. Gases up to 10^-6 mbar can be introduced in the sample chamber.
UV irradiation (Ly-alpha line: 121.6 nm). Electron irradiation (1-500 meV). Ion irradiation (0.2 - 6 keV).

XPS X-ray Photoelectron Spectroscopy
XPS is a surface spectroscopic technique for quantitative measurements of the elemental composition or stoichiometry and the chemical state of the present elements, like their oxidation state and chemical bonds. XPS is highly surface sensitive, giving chemical and binding energy information from the a narrow region close to the surface.
Growth & Synthesis
MICS Multiple Ion Cluster Source
We offer a multiple ion-cluster source operating in ultra-high vacuum devoted to the fabrication and characterization of highly controlled nanoparticles. They are produced in gas phase with high purity and controlled size, structure and stoichiometry and they can be collected in the desired coverage on arbitrary surfaces for different uses.
