Scanning tunneling spectroscopy at 5 K

Home made UHV scanning tunneling spectroscopy and microscopy system. Temperature range 5-300 K. Facilities for sample preparation and characterization in UHV, ion bombardment, low-energy electron diffraction, Auger spectroscopy. It is currently used for the measure of the spectral function of low-dimensional correlated  electron systems, such as Kondo systems on surfaces and two-dimensional Mott-Hubbard insulators. It has been used for cross-sectional STM-STS of nanostructures in semiconductors and transport measurements of single molecules with the break-junction technique..
