U. S. - Germany Cooperative Research: Investigation of Subpicosecond Dynamics of High-Temperature Superconducting Josephson Junction Structures

该奖项允许Roman Sobolewski与德国Juelich国家研究中心（Forschungszentrum）的Michael Siegel合作。该项目将通过实验确定在皮秒电脉冲或飞秒脉冲光激发下切换时结的耦合机制来研究高温超导约瑟夫森结的内在动力学特性。该研究的最终目标是开发和制造用于超快计算的高温超导器件和电路以及用于超级计算电子学的光电链路。该研究还将测试单通量量子超导约瑟夫森门的最终运行速度极限。

This award allows Roman Sobolewski to collaborate with Michael Siegel of the National Research Center (Forschungszentrum) in Juelich, Germany. The project will investigate the intrinsic dynamical properties of high-temperature superconducting Josephson junctions by experimental determination of the coupling mechanism for the junction when switched either by picosecond electrical pulses or perturbed by femtosecond-pulse optical excitations. The ultimate goal of the research is to develop and fabricate high-temperature superconducting devices and circuits for ultrafast computing and optoelectronic links for supercomputing electronics. The research will also test the ultimate limit of the operating speed of a single-flux quantum superconducting Josephson gate.
