CINT has multiple Atomic Force Microscopy (AFM) systems that can be leveraged to perform a variety of sample imaging modalities.  

AFM systems available to CINT users:

• Bruker Dimension Icon.
• Neaspec IR-neascope+fs.
• Yázhí — a home-built AFM optical access via an inverted optical microscope.

General Capabilities include:

• General Atomic Force Microscopy — topography and phase imaging.
• Nano-particle identification.
• Surface roughness characterization.

The Bruker Dimension Icon Scanning Probe Microscope supports many advanced imaging features, including:

• PeakForce® Quantitative nanomechanical mapping, with high-resolution high-stiffness upgrade.
• Electrostatic Force Sensing modalities:
  • Electro-static Force Microscopy (EFM).
  • Kelvin Force Mircroscopy (KPFM).
  • Piezoresponse Force Microscopy (PFM).
  • Scanning current-voltage microscopy.
  • Scanning Capacitance Microscopy (SCM).
• Electrochemical scanned probe microscopy.
• Low-force nanoindentation.
• Scanning Tunneling Microscopy (STM).
• Conductive/Photoconductive AFM — Peakforce Tunneling current AFM (PeakForce TUNA) with bottom illumination.
• Magnetic Force Microscopy (MFM).

The Neaspec IR-neascope+fs supports the measurement of optical properties of surfaces using scattering-scanning near-field optical microscopy (s-SNOM).  These include:

• Nano-Vis — Mapping of the near-field optical response of surfaces in the visible spectral range.
• Nano-IR — Resolution of the optical response of material surfaces in the Mid-IR spectral range using continuous wave illumination from a tunable Quantum Cascade Laser.
• Nano-FTIR — Allows for nanoscale chemical identification by combining s-SNOM with FTIR.
• Femtosecond s-SNOM: Studies dynamic processes in nanomaterials by combining pump-probe spectroscopy with nano-FTIR.
