Gain bandwidth of NbN Heterodyne Hot Electron Bolometer Superconducting Mixers made on thin SiO2/Si3N4 membrane
Övrigt konferensbidrag, 2006
We present results of the gain bandwidth investigation
of NbN HEB mixers made on 1.4 µm thick SiO2/Si3N4
stress-less membrane, and bulk-Si/SiO2/Si3N4. We have found
that the gain bandwidth of the devices made on these substrates is 0.6-0.9 GHz while on bare-Si it is 3.5 GHz. The final objective of this work is to process membrane based NbN HEB mixers for a 4x4 pixel heterodyne camera for 2.5 and 4.7 THz. SHAHIRA (Submm Heterodyne Array for HIgh speed Radio Astronomy) is a project supported by ESA.
