- Variable-temperature (VT) scanning tunneling microscope with atomic force microscopy capabilities (Omicron VT-AFM/STM), operates in an ultrahigh vacuum (UHV) environment with a base pressure of < 1E-10mbar and 55-400K. Atomic resolution is routinely obtained at room temperature and below. The AFM capabilities support a range of scanning modes. The analysis chamber also houses a LEED/Auger with an attached preparation chamber for sample cleaning and deposition (e.g. sputter cleaning, direct current heating, e-beam heating stage, metal deposition).
- Low-temperature ultrahigh vacuum scanning tunneling microscope (4K base with temperature variability) with 6 Texternal magnetic field applied normal to the sample surface. Intended for variable temperature high impact research requiring an external magnetic field (Omicron Cryo SFM).
- Variable-temperature scanning tunneling microscope with optical access (home-built optical VT-STM) operates in an UHV environment with a base pressure of < 1E-10 mbar and 55-300 K. Atomic resolution can be obtained at room temperature and below on appropriate samples. The analysis chamber also houses a LEED/Auger with an attached preparation chamber for sample cleaning and deposition (sputter cleaning, direct current heating, e-beam heating stage, metal deposition).

Synchrotron X-ray Scanning Tunneling Microscopy (SX-STM)
Synchrotron X-ray scanning tunneling microscopy (SX-STM) is a new imaging technique that uniquely combines the best of two worlds: the exceptional chemical, magnetic, and structural sensitivity of X-rays combined with the unparalleled ability of scanning probe microscopy to resolve and manipulate surfaces down to single atoms. In collaboration with the APSX-ray Science division we are developing XTIP, the world’s first dedicated synchrotron beamline for SX-STM. XTIP, located at Sector 4 of the APS, is under construction and will become operational in 2018. Until then, we provide limited beamtime at APS beamline 4-ID-C to General Users for early-science SX-STM experiments.These experiments will focus on the study of chemical and magnetic properties of nanoscale materials using SX-STM at photon energies between 500 to 2500 eV.
