Scanning Probe Microscopy

Leeds EPSRC Nanoscience and Nanotechnology Research Equipment Facility (LENNF)

LENNF houses both Atomic Force Microscopy (AFM) and Scanning Tunneling Microscopy (STM) facilities. A range of instruments and sample preparation facilities are available;

  • Colloid probe preparation facilities, UV/Ozone cleaning facilities and wet labs for simple biological and organic sample preparation
  • Veeco Instruments Nanoscope IV Multimode AFM with Temperature control unit (20-50°C)
  • Veeco Instruments Bioscope II with Nanoscope V controller
  • Veeco Instruments Bioscope I with Nanoscope IV controller
  • Veeco Instruments Dimension 3100 Nanoman with Nanoscope IV controller

The Multimode AFM is suitable for high resolution imaging of samples in air, gaseous environments and liquids. The Bioscopes sit on inverted optical microscopes allowing the possibility of simultaneous optical and AFM analysis. The Nanoman AFM is suitable for large samples and lithographic and nanomanipulation experiments.

An Omicron VT AFM/STM UHV-based high resolution STM & AFM is also available.  It has a liquid Helium flow cryostat allowing measurements to be taken over a temperature range of 10 - 1500 K. Other features include Scanning Tunnelling Spectroscopy, Magnetic Force Microscopy and Scanning Kelvin Probe Microscopy.
