G-Mode SPM

G-mode Controller and Software for Scanning Probe Microscopy

General mode (G-Mode) atomic force microscopy is based on information-theory analysis of the direct data stream coming from the microscope photodetector. It allows for full exploration of complex tip-sample interaction reconstruction into mapping of multidimensional material properties.

Specifications

  • Frequency bandwidth: Hz-MHz
  • LabVIEW software controls the gathering and saving of full photodiode data stream at 4MS/s.
  • Compatible with all AFM platforms.

Applications

Increasing the temporal resolution of electrical AFM modes such as Kelvin Probe force microscopy down to the µs time scale (has been applied to solar materials and polymers)

Allowing AI/ML analysis technique to work on big data type microscopy datasets in all spatio-temporal dimensions overcoming classical lock-in and phase locked loop processing.
