Main functions

1. PeakForce Tapping technology enables convenient acquisition of reliable high-resolution data.

2. PeakForce QNM peak force quantitative nanomechanical technology can provide multiple mechanical information, such as quantitative Young's modulus, quantitative adhesion force, quantitative sample deformation, and dissipation energy simultaneously with high-resolution morphology.

3. PeakForce TUNA peak force high-resolution current module enables simultaneous tests for high-resolution morphology, quantitative nanomechanics, and high-resolution electrical measurements.

4. The scanning capacitance microscopy (SCM) module realizes ultrafast scan imaging with rich signal channels including capacitive and deflection signals while ensuring image quality during the topography scan.

5. Equipped with a high-temperature heater and a cryogenic/heating sample stage.
