Nanosized ferroelectrics — •Izabela Szafraniak — Institute of Materials Science and Engineering, Poznan University of Technology, Poznan, Poland — Institute of Molecular Physics, Polish Academy of Sciences, Poznan, Poland

Among functional materials ferroelectrics are expected to play an important role because they find various applications in a remarkably broad spectrum of advanced electronic, electromechanical and electro-optic components. Future applications require ferroelectric structures with lateral size well below 100 nm. It is well- known phenomena that many materials change or even lose their useful properties as soon as their sizes fall below a certain limit. The ferroelectric size limit has been very important subject of research during last decades. The recent achievements will be discussed. The special emphasis will be put on fabrication ferroelectric nanostructures (including nanowires and nanotubes), multiferroic materials and relations between nanostructure sizes and properties (including role of misfit dislocation on switching behaviour).
