Real-time observation of self-assembling nanostructures of Langmuir-Blodgett films of vinylidene fluoride-trifluoroethylene copolymer by Atomic Force Microscopy.

Abstract
Annealing studies have shown that ferroelectric polymer Langmuir-Blodgett (LB) films less than 10 nm thick undergo drastic morphology change after annealing in the crystalline ferroeletric phase [M. Bai \textit{et al.}, \textit{Appl. Phys. Lett. }\textbf{85}, 3528 (2004)] During annealing in the crystalline paraelectric phase, continuous films self-assemble into disk shape features, nanomesas, with approximately 9 nm thickness and 100 nm diameter. The nanomesa self-assembly was observed in real time with an Atomic Force Microscope, which was equipped with a heating stage. This results show that the nanomesas formed during annealing agree well with nanomesas observed in ferroelectric phase at room temperature after annealing in the paraelectric phase.
