“…Their exceptionally large piezoelectric compliances, pyroelectric coefficients, dielectric susceptibilities and electro-optic properties make them very attractive for nanotechnologyrelated applications such as high energy density capacitors, pyroelectric thermal imaging devices, gate insulators in transistors, electro-optic light valves, thin-film memory elements, multiferroic transducers, energy harvesters, etc. (Alpay et al, 2009, Nonnenmann & Spanier, 2009Scott, 2007;Leionen et al, 2009) The most common ferroelectric materials in commercial applications are ceramics, such as lead zirconate-titanate (PZT), barium titanate (BTO), calcium-copper titanate CaCu 3 Ti 4 O 12 (CCTO), sodium niobate (NaNbO 3 ), among others, which present a high dielectric constant, high dipole moment and high electromechanical coupling coefficient. Ferroelectric ceramics have been recently synthesized by solvothermal (Wada et al, 2009), coprecipitation (Hu, et al, 2000), sol-gel (Kobayashi et al, 2004), and template assisted methods (Rorvik et al, 2009), in order to obtain nanostructured materials.…”
