Title: Oriented niobate ferroelectric thin films for electrical and optical devices and method of making such films

Abstract

Sr{sub x}Ba{sub 1{minus}x}Nb{sub 2}O{sub 6}, where x is greater than 0.25 and less than 0.75, and KNbO{sub 3} ferroelectric thin films metalorganic chemical vapor deposited on amorphous or crystalline substrate surfaces to provide a crystal axis of the film exhibiting a high dielectric susceptibility, electro-optic coefficient, and/or nonlinear optic coefficient oriented preferentially in a direction relative to a crystalline or amorphous substrate surface are disclosed. Such films can be used in electronic, electro-optic, and frequency doubling components. 8 figs.
