– Organic/inorganic MBE growth (100-1200 K)
– LEED/AES
– Residual gas analizyer

A variable temperature scanning tunneling microscope operating between 100K and 400K, based on the commercial Specs STM 150 Aarhus. System specifications:

– Operating temperature: 90-400 K
– Sample preparation chamber (sputter gun, gas inlets, annealing up to 1200 K)
– Organic/inorganic MBE growth
– Residual gas analizyer
– Can be coupled to BOREAS (XAS/XMCD) beamline at ALBA for in-situ measurements (see below)

 

ICN2

We combine the local characterization achieved by STM by XPS and ARPES measurements carried out in a common ICN2 facility. The equipment consists on:
– PHOIBOS 150 analyzer from SPECS
– He source + monochromator (He I at 20.2 eV, HeII at 40.8 eV)
– Al and Ag sources (Al Kα at 1487 eV, Ag Lα at 2983 eV)
– Manipulator with a T range from 30-1200 K
– Sample preparation chamber (annealing up to 1000ºC)
– Organic/inorganic MBE growth
– LEED/AES

EXTERNAL

In addition to routine access to several international synchrotron radiation facilities, a collaborative project with the BOREAS beamline at ALBA enables us to couple the VT-STM of our group to the two endstations, HECTOR for X-ray absorption (NEXAFS, XMLD, XMCD) and MARES for resonant scattering (GISAX, SXRS). This set-up provides in-situ sample preparation and characterization capability, opening the possibility to perform magnetic measurements in nanostructures with controlled size, shape and density, organic/inorganic thin films, and other complex nanostructures.
