Zusammenfassung

The terahertz regime belongs to the least explored one in the electromagnetic spectrum but promises a wide range of applications in material characterization, product inspection, imaging or medical imaging, to name a few. Besides optimizing existing concepts, the advent of novel materials like graphene or topological insulators which are gapless or feature a small gap comparable to the energy of THz radiation offers new opportunities to look for novel and sensitive detectors. Such detectors and detector systems, which can be used, e.g., for imaging spectroscopy are an indispensable ingredient ...
