Terahertz electronics on the atomic scale using intrinsic Josephson junctions in cuprate superconductors

该项目旨在利用传输测量、直接电磁波探测和低温扫描激光显微镜相结合的方法，研究和优化在本征约瑟夫森结堆或堆阵列中产生太赫兹电磁波的方法。该项目结合了研究小组的专业知识，以成像超导结构中的电流和电场分布(Tübingen)，以及制造全超导本征约瑟夫森堆栈和堆栈阵列的技术和设备(筑波)。我们的目标是了解太赫兹电磁波的产生机制，并从可调谐、功率输出和功能方面优化本征约瑟夫森结堆栈结构。

The project aims on the investigation and optimization of THz electromagnetic wave generation in intrinsic Josephson junction stacks or arrays of stacks, using a combination of transport measurement, direct electromagnetic wave detection and Low Temperature Scanning Laser Microscopy. The project combines the specialties of the research groups to image current and electric field distributions in superconducting structures (Tübingen) and the know-how and facilities to fabricate all-superconducting intrinsic Josephson stacks and arrays of stacks (Tsukuba). The goal is to understand the mechanism of THz electromagnetic wave generation and optimize the intrinsic Josephson junction stack structures with respect to tunability, power output and functionality.
