ABSTRACTDomain stabilization in epitaxial potassium niobate films deposited by metalorganic chemical vapor deposition was studied. Stabilization was examined for films deposited on substrates with different coefficients of thermal expansion. X-ray diffraction of KNb03 films deposited on (100) MgAl204, (r) A1203, and (100)pseudocubic YAIO3 substrates shows a mixed domain structure consisting of (110) and (001) domains. However, KNb03 thin films deposited under identical conditions on (100) MgO, (100) SrTi03, and (100)pseudocubic LaA103 substrates exhibited only a single domain variant. A direct correlation between (001) domain volume fraction in the as-deposited KNb03 films and calculated strain resulting from thermal mismatch is observed.
