Room-Temperature STM

This UHV machine is the workhorse of our group. The STM delivers excellent atomic resolution since 1991.

Besides the STM, the analysis chamber also features a hemispherical analyzer for XPS (x-ray photoelectron spectroscopy) and LEIS (low-energy ion scattering), a cylindrical mirror analyzer with coaxial electron source for AES (Auger electron spectroscopy) and LEED optics (low-energy electron diffraction). The preparation chamber is equipped with an ion source for sputtering, three electron-beam evaporators, a retractable gas doser with a microcapillary plate and a gas cracker for atomic oxygen or hydrogen. Sample heaters (electron bombardment of the sample plate, up to 1200 °C) are available in both chambers.
