PeakForce TUNA

Highest Resolution Current Mapping on the Most Fragile Samples

PeakForce TUNA logo300x56

PeakForce TUNA™ is an ideal method for probing conductivity of fragile samples such as organic photovoltaics, conductive nanotubes, and nanoparticles. It overcomes the limitations of traditional contact-mode-based conductive AFM techniques, which are severely restricted by sample damage or probe tip contamination from CAFM lateral forces. PeakForce TUNA provides direct, precise force control and eliminates lateral forces. This enables routine highsensitivity and high-resolution current imaging.


Now users can benefit from the full fA to μA current range, directly correlated quantitative nanomechanical property imaging with PeakForce QNM®, and the ease-of-use of ScanAsyst®, all with one module. PeakForce TUNA can also be integrated with environmental control to regulate oxygen and water levels down to ppm to accommodate the most sensitive samples.


PeakForce TUNA offers:

  • Highest resolution current mapping on the most fragile samples
  • Unmatched repeatability and consistency in nanoelectrical measurements
  • Correlated nanomechanical and nanoelectrical properties
