Fabrication and Characterization of YBCO Thin Films for Photoinduced Superconductivity Studies

9414466将对用于光致超导的YBCO薄膜进行费德里奇生长和电学/光学表征。在高转变温度的铜氧化物超导体中，与预期相反的是，实验证据表明，光脉冲与超导体的相互作用实际上增强了材料的超导性能。这项研究的目的是通过将光致超导机制与样品的发光、光学+电学性质相关联，在实验上区分不同的竞争模型，并将这些知识应用于新型光控超导器件的设计和演示。该项目将支持一名博士生，他将在新泽西州蒙茅斯堡的陆军EPSD研究设施进行YBCO薄膜制造和霍尔测量。***

9414466 Federici Growth and electrical/optical characterization of YBCO thin films for photoinduced superconductivity will be carried out. In high transition temperature copper oxide superconductors, contrary to expectation, experimental evidence has indicated that interaction of a light pulse with the superconductor actually enhances the superconducting properties of the material. The purpose of this research is to experimentally differentiate between competing models of the photoinduced superconductivity mechanism by correlating it with the sample's luminescent, optical + electrical properties, and to apply that knowledge in the design and demonstration of novel optically-controlled superconducting devices. The project will support a PhD student who shall perform YBCO thin fabrication and Hall measurements at the Army's EPSD research facility in Fort Monmouth, NJ. ***
