dc.description.abstract | Because of the presence of OH- and H2O in the KN unit cell, tetragonal KNbO3 (KN) nanowires were formed when the synthesis was carried out at 120 degrees C for 48 h. However, when the fabrication was conducted at high temperatures (>= 150 degrees C) or at 120 degrees C for a long period of time (>= 72 h), orthorhombic KN nanowires were formed. Moreover, the KN nanowires synthesized at 120 degrees C for 60 h showed a morphotropic phase boundary (MPB) structure in which both tetragonal and orthorhombic structures coexisted. Tetragonal, orthorhombic and MPB KN nanowires were also grown on the Nb5+-doped SrTiO3 substrate, and their d(33) values were measured for the first time. A tetragonal KN nanowire exhibited a d(33) value of 23.5 pm V-1, which is larger than that of the orthorhombic KN nanowire (11.6 pm V-1), probably because of the softening effect of the metal vacancies. The MPB KN nanowires exhibited a larger d33 value of 40.0 pm V-1. The d(33) values of KN nanowires increased to 104.5, 137.1 and 146.0 pm V-1 for the orthorhombic, tetragonal and MPB KN nanowires, respectively, after the KN nanowires were poled along the [1 0 0] direction by application of a DC voltage of 10 V.
