摘要:

AmorphousKNbO3films are prepared by a low-cost sol–gel method. These films show a smooth surface morphology and have good waveguiding properties. Ferroelecticlike hysteresis loops are observed in these amorphousKNbO3films with a remanant polarization of about6&mgr;C/cm2.After corona poling, a stable effective second harmonic generation coefficient of 0.523 pm/V is achieved. ©1997 American Institute of Physics.
