Preparation and Characterization of Oxide and Sulfide Thin Films

这一更新建议将应用分子前体喷雾热解的新技术，以制备各种基底上的氧化物和硫化物薄膜。该技术由首席研究员开发，将应用于氧化铬、氧化镓和氧化锆，以及掺杂各种磁性离子的硫化锌和硒化锌。薄膜的物理表征将包括光学显微镜、电子和x射线衍射以及电子电阻率测量。化学表征将包括对氧化和/或还原稳定性的研究，以及相应成分的薄膜和块状材料所表现出的特性的相关性。

This renewal proposal will apply a novel technique of spray pyrolysis of molecular precursors to the preparation of thin films of oxides and sulfides on various substrates. The technique, developed by the Principal Investigator, will be applied to chromium oxide, gallium oxide, and zirconium oxide, and to zinc sulfide and zinc selinide doped with various magnetic ions. Physical characterization of the films will include optical microscopy, electron and x-ray diffraction and electronic resistivity measurements. Chemical characterization will include a study of stability towards oxidation and/or reduction, and a correlation of properties exhibited by the films and bulk materials of corresponding compositions.
