<p><P>PROBLEM TO BE SOLVED: To provide a low temperature method for forming a film of potassium niobate, by which a thin film of potassium niobate can be formed at a low temperature without using a specific device necessitating vacuum or high energy or an expensive specific raw material. <P>SOLUTION: A single crystal of K<SB>2</SB>NbO<SB>3</SB>F is allowed to deliquesce on a substrate and then dried. When the single crystal is allowed to deliquesce, preferable humidity and temperature are≥60% and 0-50°C, respectively. Thereby, a high quality single crystal thin film of potassium niobate can be formed at room temperature. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
