National Institute Of Materials Physics - Romania
Laboratory of Surface and Interface Science

Main research directions:

  • Surface and interface analysis by photoelectron spectroscopies (XPS‒ESCA, ARUPS, spin-resolved PES, PED) in situ electron diffraction (LEED, RHEED), Auger electron spectroscopy (AES),  scanning tunneling microscopy and spectroscopy (STM‒STS), photoelectron spectromicroscopy, low energy and photoemission electron microscopy (LEEM‒PEEM);
  • Surfaces, thin films and heterostructure preparation by molecular beam beam epitaxy (MBE) or other vacuum evaporation techniques.

New subjects:

  • analysis of ferroelectric surfaces, band bending in heterostructures;
  • molecular reactions at ferroelectric surfaces;
  • in plane conduction properties of 2D systems on ferroelectric surfaces;
  • ‘2D nanoreactors', molecular reactions with reactants stabilized between graphene layers and substrates;
  • spin asymmetry in band structure of 2D systems;
  • photocatalysts with internal junctions;
  • multiferroic structures with indirect exchange or coupling through charge accumulation;
  • theoretical developments in the area of ferroic thin films (ferroelectric, ferromagnetic);
  • development of new devices operating in ultrahigh vacuum (effusion cells, evaporators, manipulators);
  • development of software packages for data analysis.
