We report the synthesis of KNbO(3) nanowires (NWs) with a monoclinic phase, a phase not observed in bulk KNbO(3) materials. The monoclinic NWs can be synthesized via a hydrothermal method using metallic Nb as a precursor. The NWs are metastable, and thermal treatment at ∼450 °C changed the monoclinic phase into the orthorhombic phase, which is the most stable phase of KNbO(3) at room temperature. Furthermore, we fabricated energy-harvesting nanogenerators by vertically aligning the NWs on SrTiO…

Growth kinetics of one-dimensional KNbO3 nanostructures by hydrothermal processing routes.
TLDR
A model taking into account the cube-based morphology of the nanostructures, their defects as the KOH proportion in the starting solution increases, and the partial depletion of species in the solution at the kink regions is proposed allows the morphological evolution of the Nanowires and nanofingers to be successfully reproduced, shedding light on the origin of their highly anisotropic growth.

TLDR
By carefully examining nonlinear properties of (XNbO(3)) nanowires the authors suggest which type of wires are best suited for the given application and demonstrate for the first time wave-guiding of SHG signal in all three types of alkaline niobate nanowire.

TLDR
Evidence of a previously unreported ferroelectric ground state of monoclinic symmetry is provided and the tuning of the polarization's direction is tuned by varying factors inherent to the nanoscale.
