Abstract

KNbO3 thin films have been deposited from K(OMe)/Nb(OMe)5 sols onto (100) MgO substrates. Microstructural changes were observed relative to stoichiometry, aging, and the hydrolysis temperature. The production of single phase, oriented films has been demonstrated, and was found to be strongly dependent on process conditions. The films were characterized by XRD, TEM, SEM, EDS, and Raman spectroscopy.
