Abstract :
Thin films of LiNbO have been RF sputter deposited on silicon and sapphire substrates. A number of analytical techniques have been used to determine the physical structure of these films. This analysis shows that the resulting films are stoichiometric LiNbO/sub 3/ and oriented polycrystalline in nature. It is now possible to consider applications which utilize the unique properties of these films.<>
