Volatile Metal Chelates for the Deposition of Superconduct- ing Materials on Ductile Matrices

这项调查将研究几种不同的挥发性金属 可能形成高过渡态薄膜的螯合物 高温超导材料时，由金属- 有机化学气相沉积（MOCVD）。 这些研究将 包括β-二酮的合成和表征， 钡铜和几种稀土金属 这些化合物作为 以及现有的相关已知化合物将用于 确定薄膜沉积所需的条件， 氧化以在衬底（例如 铜和柔性熔融石英。 结果的表征 材料将通过粉末X射线衍射和测量来制备。

This investigation will study several different volatile metal chelates that are likely to form thin films of high transition temperature superconducting material when deposited by metal - organic chemical vapor deposition (MOCVD). These studies will include the synthesis and characterization of beta-diketonates of barium, copper, and several rare-earth metals. These compounds as well as related known compounds that are on-hand will be used to determine the conditions necessary for thin film deposition and oxidation to yield superconducting layers on substrates such as copper and flexible fused-silica. Characterization of the resulting material will be made by powder x-ray diffraction and by measurement.
