- 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).
- 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.
