Advances in lead-free piezoelectric materials for sensors and actuators.
Sensors (Basel.) 10(3) , 1935-54, (2010) Piezoelectrics have widespread use in today's sensor and actuator technologies. However, most commercially available piezoelectric materials, e.g., Pb [Zr(x)Ti(1-x)] O(3) (PZT), are comprised of more than 60 weight percent lead (Pb). Due to its harmful effect... |

Optical and dielectric properties of isothermally crystallized nano-KNbO3 in Er3+-doped K2O-Nb2O5-SiO2 glasses.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 75(1) , 243-50, (2010) Precursor glass of composition 25K(2)O-25Nb(2)O(5)-50SiO(2) (mol%) doped with Er(2)O(3) (0.5 wt% in excess) was isothermally crystallized at 800 degrees C for 0-100 h to obtain transparent KNbO(3) nanostructured glass-ceramics. XRD, FESEM, TEM, FTIRRS, dielec... |

Nonlinear optical response in single alkaline niobate nanowires.
Nano Lett. 11(6) , 2517-21, (2011) We have synthesized and characterized three types of perovskite alkaline niobate nanowires: NaNbO(3), KNbO(3), and LiNbO(3) (XNbO(3)). All three types of nanowires exhibit strong nonlinear response. Confocal imaging has been employed to quantitatively compare... |

Growth of single-crystalline KNbO3 nanostructures.
J. Phys. Chem. B 110(1) , 58-61, (2006) This communication reports on the growth of highly uniform KNbO3 nanowires exhibiting a narrow diameter distribution around 60 nm and a length-to-width ratio up to 100. The nanowires were prepared by a hydrothermal route, which enables simple, gram-scale prod... |

Flexible pyroelectric nanogenerators using a composite structure of lead-free KNbO(3) nanowires.
Adv. Mater. 24(39) , 5357-62, (2012) Pyroelectric nanogenerators fabricated using a lead-free KNbO(3) nanowire-PDMS polymer composite are reported for the first time. The voltage/current output of the nanogenerators can be controlled by electric fields and enhanced by increasing the rate of chan... |

Piezoelectric properties of (K,Na)NbO3 thin films deposited on (001)SrRuO3/Pt/MgO substrates.
IEEE Trans. Ultrason. Ferroelectr. Freq. Control 54(12) , 2562-6, (2007) (K(x),Na(1-x))NbO(3) (KNN) thin films were deposited on (001)SrRuO(3)/(001)Pt/(001)MgO substrates by RF-magnetron sputtering, and their piezoelectric properties were investigated. The x-ray diffraction measurements indicated that the KNN thin films were epita... |

Synthesis of monoclinic potassium niobate nanowires that are stable at room temperature.
J. Am. Chem. Soc. 135(1) , 6-9, (2013) 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 t... |
