Equipment
Low-Temperature Scanning Tunneling/ Atomic Force Microscope (STM/AFM)
The Infinity system (Sigma Surface Science) is currently the working horse of our group.
Based on the qPlus sensor design, the microscope allows for high-resolution STM/AFM and extensive spectroscopy experiments.
A pulse tube cooler is employed to cool the microscope to a temperature of about 8.5 K. An additional UHV chamber, equipped with several evaporators and a low energy electron diffraction (LEED) setup, is dedicated to sample preparation.
Near-Ambient Pressure X-ray Photoelectron Spectroscopy (NAP-XPS)
The NAP-XPS instrument (Specs GmbH) offers the possibility to carry out XPS experiments from UHV up to 20 mbar. Thanks to its design, both solid/gas (up to 500°C) and solid/liquid interfaces can be investigated, in addition to cryogenic samples (down to -180°C). The instrument is located at the Institute of Physical Chemistry.
