Università Cattolica del Sacro Cuore


The Surface Science and Spectroscopy Lab is mainly based on an experimental set-up for photoemission spectroscopy and thin film and multilayer deposition. The Lab has been funded by the Catholic University, the Italian Ministry for Research through national research projects, the INFM institute, and also by private contributions.

The system is composed of three connected chambers operating in UHV.

  • The first analysis chamber is equipped with an hemispherical analyser and a 32-channel detector, a twin anode and a monochromatized X-ray source, a high intensity UPS source, and an LN2-cooled manipulator with five degrees of freedom.
  • The second analysis chamber is equipped with a LEED system and optical windows.
  • The third (deposition) chamber is equipped with e-beam evaporators for single- and multi-layer deposition.

The whole system can operate in UHV conditions at a base pressure better than 10-10 mbar.

A second UHV system is now working for ARPES and PED spectroscopy studies. The system is equipped with a VG-SCIENTA R3000 analyser, a twin anode source, a UV lamp.

The laboratory is also equipped with a RF sputtering system for thin film deposition and a MOKE apparatus for magneto-optical studies on thin films.
