Figure 1: PbTiO3 nanodots on a Nb-doped SrTiO3 substrate.
From: Anomalous domain periodicity observed in ferroelectric PbTiO3 nanodots having 180° stripe domains
(a) Dip-pen nanolithography (DPN) of PbTiO3 nanodots. (b) An AFM image for PbTiO3 nanodot array having four different size classes. The array was formed by the DPN method. (c) Side length and thickness of PbTiO3 nanodots as a function of the dip-pen deposition time. (d) d33 value and the coercive electric field (Ec) plotted as a function of the nanodot size, where A, B, C, and D indicate the dot size in (b).
