Characterization

  • 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-10 mbar and 55-400 K. 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) (for details contact the instrument custodian).
  • Low-temperature ultrahigh vacuum scanning tunneling microscope (4K base with temperature variability) with 6T external magnetic field applied normal to the sample surface. Intended for variable temperature high impact research requiring an external magnetic field (Omicron Cryo SFM) (for details contact the instrument custodian).
  • 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) (for details contact the instrument custodian).
  • Low-temperature scanning tunneling microscope (LT-STM, Createc) (for details contact the instrument custodian).
  • Scanning probe microscope Veeco MultiMode 8 [contact or tapping mode, fluid imaging, low-current scanning tunneling microscopy, magnetic force microscopy, variable temperature imaging (-30-250°C), PeakForce tapping mode and PeakForce quantitative nanomechanical mapping] (for details contact the instrument custodian).
  • Characterization of electrical transport properties at the nanoscale via state-of-the-art UHV nanoprobes (4-tip SEM Omicron UHV Nanoprobe)
  • Internal/external quantum efficiency measurement system (Oriel IQE-200)
  • Laser scanning interferometric microscope (for details contact the instrument custodian)
  • Luminescence spectrometer (Perkin-Elmer LS 55)
  • Magnetic and physical properties characterization suite ( Keithley 4200-SCS/F Semiconductor Parameter Analyzer, Quantum Design PPMS-9 and MPMS XL)
  • Optical microscope (Zeiss Axio Imager Z1 M Upright)
  • Rheometer (AntonPaar Physica MCR301). This can be accessed alone or as part of the joint CNM/APS rheometry small angle x-ray scattering x-ray photon correlation spectroscopy system (Rheo-SAXS-XPCS) housed at Sector 8-ID-I of the APS; proposals for the latter system are accepted via the APS user proposal portal. Please contact the custodian with further questions.
  • Solar simulator (Oriel)
  • Thermal analysis [differential scanning calorimetry (Mettler Toledo 823) and thermogravimetric analysis (Mettler Toledo 851)]
  • Ultraviolet-visible-near-infrared spectrometer (Perkin-Elmer Lamda 950)
  • X-ray diffractometer (Bruker D8 Discover, point detector, VÅNTEC-1 linear detector; Bragg-Brentano powder, Grazing incidence, high-resolution four-circle, reciprocal space mapping, reflectivity, rocking curves)
