PEARL - X03DA:
PEARL is dedicated to the structural characterisation of local bonding geometry of molecular adsorbates on metal or semiconductor surfaces, of nanostructured surfaces, and of surfaces of complex materials.
Photoemission and Atomic Resolution Laboratory
The laboratory features a soft X-ray beamline with an angle-resolved photoelectron spectrometer for angle-scanned and photon energy-scanned X-ray photoelectron spectroscopy (XPS, ARPES) and diffraction (XPD/PhD). A low-temperature scanning tunnelling microscope (STM) provides a complementary real-space view of the sample. In-situ surface preparation facilities, organic evaporators, and ports for user-supplied equipment are also available.
The beamline is operational and open to general users, cf. User Information. For further information please refer to our beamline article, or contact the beamline scientist, firstname.lastname@example.org.
The PEARL beamline is operated by the Microscopy and Magnetism Group. It has been developed and funded in collaboration with a consortium of five Swiss research institutions.
