Digital Teaching
The lecture is held as a combined digital and face-to-face course. During the semester, regular lecture dates will take place in Zoom. At the end of the semester, a practical demonstration of high-temperature superconductors as well as the detailed possibility of Q&A will be given on 2 presence dates to be agreed upon. Individual face-to-face oral exams will conclude the lecture.
