Installation is composed of low-temperature ultrahigh vacuum scanning tunneling microscope GPI CRYO, allowing the surface to carry out research in the temperature range 5-300 K.

To prepare the object of study and preliminary diagnosis of a surface ion source, low-energy electron diffractometer, the mass spectrometer and an Auger spectrometer. There are also the natural gas, allowing the gas to file directly in bunches in the analysis area.

Experimental methods for studying

The surface structure

STM (scanning tunneling microscopy). Allows to obtain images of the surface with atomic resolution and to carry out the spectral identification of the atoms in the temperature range 5-300 K.

LEED (Low Energy Electron Diffraction) The classic method for the determination of surface structure on the analysis of diffraction images. Used to characterize the structures on the surface of single crystals

EELFS (Extended Energy Loss Fine Structure). The method is based on an analysis of the extended fine structure in the spectra of electron loss caused by interference at the output of an electron from an atom of a solid. Allows you to define the local structure around the selected type of atoms.

Spectroscopy of the surface

AES (Auger Electron Spectroscopy). The standard measurement of the elemental composition of the surface. The use of factor analysis for the processing of the Auger spectra provides information about the chemical composition of the surface.

TDMS (Thermodesorption mass spectrometry). The classical method of studying surface chemical reactions. Allows you to determine the composition and energy termodesorbed compounds.
