FIG. 1.

Interfacial force-distance curves for normal force (solid circle) and friction force (open circle) taken at a relative humidity of 30% at a tip-approaching speed of 3 nm/s while modulating the sample laterally with an amplitude of ∼1 nm at the frequency of 100 Hz. The solid lines represent fitting curves with an altered entropic chain model—the freely jointed chain (FJC) model—for each layering structure.

FIG. 2.

A comparison of fitting methods between linear fitting (green dashed line) and the FJC fitting model (red solid line). (Inset) Correlation coefficient (R) vs. tip-sample distance for the FJC fitting (open red circles) and linear fitting (closed green circles).

Image of FIG. 3.
FIG. 3.

Number of chains (solid circles) with respect to the number of monomers in each layering structure. The solid line is a fitting curve ( with ) and its extrapolations. In this data set, (), and λ were found to be 389.40 and 12.86, respectively.
