Figure 5: PFM images for the thin-film of 1.
From: Quinuclidinium salt ferroelectric thin-film with duodecuple-rotational polarization-directions
(a,c) Vertical PFM phase images. (b,d) Vertical PFM amplitude images. (e,f) Phase and amplitude signals as functions of the tip voltage for a selected point, showing local PFM hysteresis loops.
