Dielectric materials for high frequency detector applications — •Theo Scherer — KIT Karlsruhe, IAM-AWP

Superconducting detectors like Hot-Electron-Bolometers (HEBs) are used for the detection of signals in radioastronomy in the range of several hundrets of GHz up to THz. The dielectric properties and the phonon-conductance of substrate materials is essential for the 3dB-bandwidth of such a device. A comparison of different appropriate dielectrics is shown and the best candidates for real sensor devices will be discussed.
