SmartLab

The integrated spectromicroscopy laboratory, SmartLab, is a facility of the Physics Department of Sapienza University of Rome. This lab has been developed to perform spectromicroscopy experiments (µ-Raman, µ-photoluminescence and X-ray photoemission spectroscopies) in a controlled atmosphere, free of contaminants (ultra-high vacuum, UHV), allowing to probe systems even at cryogenic regimes (10 K). The specific design of the manipulation of the samples give access to a spatial resolution of the order of microns (XPS) and sub-micron (µ-Raman/PL). Such a park of techniques is suitable for a complete characterization of the vibrational and electronic properties of several systems, especially low-dimensional materials.

The SmartLab apparatus is composed by three linked UHV chambers (base pressure < 2 E-10 mbar), namely a preparation chamber for sample treatments, an analysis chamber for X-ray photoemission and a Raman chamber, hosting a  UHV-compatible objective, for micro-raman and micro-photoluminescence spectroscopy in UHV regime.
