    Electrical Modes
    For engineers and researchers that need accurate data on conductance, sample resistance,
    and other electrical and topographic properties, Park offers a range of electrical scanning modes.

Piezoelectric Force Microscopy (PFM)

Our patented PFM mode accurately measures electric domain structures such as polarity in ferroelectric or piezoelectric samples. This mode includes independent control of an applied AC and DC bias, and local amplitude/phase vs. DC bias spectroscopy.
