| Title: | Synthesis, characterization and ferroelectric properties of lead-free K₀.₅Na₀.₅NbO₃nanotube arrays | Authors: | Zhou, D Gu, H Hu, Y Tian, H Wang, Z Qian, Z Wang, Y |
Issue Date: | 1-Jun-2011 | Source: | Journal of applied physics, 1 June 2011, v. 109, no. 11, 114104, p. 1-5 | Abstract: | Lead-free K₀.₅ Na₀.₅ NbO₃(KNN) nanotube arrays were synthesized by a sol-gel method with anodic aluminum oxide templates. The obtained KNN nanotubes exhibited a polycrystalline and monoclinic perovskite structure with diameters of ~200 nm and wall thickness of ~30–40 nm, respectively. The polarization-electric loop curve of the nanotubes array were examined showing the values of 2Pᵣ and 2E[sub c] at about 3.4 μC/cm² and 13 kV/cm, respectively, under a maximum electric field of 12.5 kV/cm. The piezoelectric characteristics of individual KNN nanotube array was also identified through piezoresponse force microscopy. | Keywords: | Dielectric hysteresis Dielectric polarisation Ferroelectric materials Nanofabrication Nanotubes Piezoelectricity Potassium compounds Sodium compounds Sol-gel processing |
