Thermal Analysis: (Application Module)
Enables the user to select any point (or series of points) on the AFM image to obtain localized transition temperatures, i.e. Tg and Tm, image the transition temperatures across the sample surface via the mode of Transition Temperature Microscopy (TTM) and collect maps of the sample surface showing variation in relative thermal conductivity or relative temperature across the surface (SThM). Available on all Anasys systems and as an addition to select third-party AFMs.

The data from the PS (red) and PMMA (green) clearly differentiate the two materials. Also shown is data from a thin film of PS on PMMA (blue) showing the initial penetration of the PS followed by the melting of the PMMA.

Lorentz Contact Resonance Mode:
(Software options, probes & samples)

Allows the user to study molecular orientation with nanoscale spatial resolution by changing the input polarization of the IR light while studying the associated changes in the nanoscale IR spectra and/or chemical maps at a certain wavenumber. Available on all Anasys systems.

Conducting AFM (CAFM): (Application Module)
Allows the user to obtain simultaneous height and current flow maps of the sample surface. Available on all Anasys systems.
