An integrated ultra-high vacuum apparatus for growth and in situ characterization of complex materials

Here we present an integrated ultra-high vacuum apparatus – named MBE-Cluster – dedicated to the growth and in situ structural, spectroscopic and magnetic characterization of complex materials. Molecular Beam Epitaxy (MBE) growth of metal oxides, e.g. manganites, and deposition of patterned metallic layers can be fabricated and in situ characterized by reflection high-energy electron diffraction (RHEED), low-energy electron diffraction (LEED) - Auger Electron Spectroscopy, X-ray photoemission spectroscopy (PES) and azimuthal longitudinal magneto-optic Kerr effect (MOKE). The temperature can be controlled in the range from 5 to 580 K, with the possibility of application of magnetic fields H up to ±7 kOe and electric fields E for voltages up to ±500 V. The MBE-Cluster operates for in-house research as well as user facility in combination with the APE beamlines at Sincrotrone-Trieste and the high harmonic generator (HHG) facility for timeresolved spectroscopy.
