Surface Shape Phase Surface Shape + Phase
A water mixture of cellulose nanofiber (CNF) and polyvinylpyrrolidone (PVP) was observed electrospun onto a silicon
substrate. The surface shape image shows the cylindrical shape of the fibers and the phase image shows physical
property differences of CNF and PVP fibers as differences in contrast.

Surface Shape Z-Position ʦnmʧ
A patch-shaped lipid membrane about 6 nm thick was observed (arrow) near the center of the surface shape image
(left). The force curve acquired from on top of the lipid membrane (right) indicates the variations in force generated
as the probe penetrated the membrane.

Surface Shape Surface Shape + Amplitude Surface Shape + Phase
BaTiO3, a strong dielectric, was observed using the piezoelectric force mode (PFM).
The amplitude and phase images clearly show the polarized domain structure.
