This paper reports on the activities carried out by Airbus DS SAS, OMMIC SAS and ACST GmbH during the ESA study “Micro and Millimetre-Wave Detectors” A081ET03. Two European technologies for direct detection have been developed and detectors have been designed, manufactured and characterized up to 166GHz, with performances comparable to non-European devices.
We demonstrate a W-band bolometer based on a platinum nano-strip which is integrated with a waveguide probe on a polymer substrate. We measure a high thermal response of 49000 K/W thanks to the small size of the Pt resistor and the thermal properties of the polymer. Furthermore, its small thermal capacity allows to decrease the time constant to 2.2 ms. A good matching in the entire W-band is achieved...
To ensure the high performance of graphene-based field effect transistors (GFETs) on flexible substrates, an uniform and manufacturable dielectric film with good electrical properties is needed. Thus, electrical characterization of the dielectric film on graphene on flexible substrates is very important for the development of flexible electronics based on GFETs. Here, we have fabricated and characterized...
