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.

该项目旨在研究和优化本征约瑟夫森结叠层或叠层阵列中的太赫兹电磁波产生，使用输运测量，直接电磁波检测和低温扫描激光显微镜的组合。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（蒂宾根）以及制造全超导本征约瑟夫森堆栈和堆栈阵列（筑波）的专业知识和设施。目标是了解太赫兹电磁波产生的机制，并优化本征约瑟夫森结堆叠结构的可调谐性，功率输出和功能。
