Figure 2: PbTiO3 nanodots having 180° stripe domains.
From: Anomalous domain periodicity observed in ferroelectric PbTiO3 nanodots having 180° stripe domains
(a) PFM images of the five selected nanodots with different lateral sizes. (b) A PFM line profile of the PbTiO3 nanodot having a lateral dimension of 185 nm as an example. (c) AFM line profiles of the four selected nanodots with different lateral sizes, where A, B, C, and D denote the lateral size (i.e., side length) of 45, 60, 100, and 150 nm, respectively.
