Abstract
Infrared detectors for the long-wave infrared range (LWIR) based on nano structured thermocouples exhibit response times in the order of picoseconds and will open new areas of applications in THz broadband communication systems. We investigate the thermal dynamics of nano-thermocouples for a substrate heated by a nano structured thermocouple patch. Due to its low thermal capacity a mesoscopic thermocouple is an extremely fast square-law detector with cutoff frequencies up to several hundred GHz.
