A thin film of uranium oxide was deposited by polymer assisted deposition on a single crystal lanthanum aluminate - strontium aluminum tantalate substrate. The deposition resulted in formation of epitaxial thin film of uranium oxide, which could be attributed to α-U₃O₈ or α-UO₃. X-ray diffraction revealed preferential orientation along (100) in case of α-U₃O₈ or (001) for α-UO₃ for the thin film. A combination of x-ray and neutron reflectometry proved the sample to be α-U₃O₈. The film was of 17 nm thickness covered by a capping layer. The less dense capping layer could be a manifestation of surface water adsorbed on the sample.

聚合物辅助沉积法沉积的氧化铀薄膜的生长和表征

通过聚合物辅助沉积在单晶铝酸镧-钽酸锶铝衬底上沉积氧化铀薄膜。沉积导致氧化铀外延薄膜的形成，这可能归因于α-U ₃ O ₈或α-UO ₃。X 射线衍射揭示了在α-U ₃ O _{8 的}情况下沿（100）或对于薄膜的α-UO _{3 的}（001）优先取向。X 射线和中子反射法的组合证明样品是 α-U ₃ O ₈。该膜厚度为 17 nm，被覆盖层覆盖。较低密度的覆盖层可能是表面水吸附在样品上的表现。
