We have measured the device length and temperature dependence of the intermediate frequency (IF) bandwidth and noise of hot-electron bolometer (HEB) mixers made from a high-T c superconductor. Mixer devices with lengths (L) between 50 nm and 1 μm we

Superconductive hot-electron bolometer (HEB) mixers have been built and tested in the frequency range from 1.1 THz to 2.5 THz. The mixer device is a 0.15 - 0.3 micrometer microbridge made from a 10 nm thick Nb film. This device employs diffusion as a

High frequency detector and circuit applications often require device fabrication on medium-to-low dielectric constant substrates ((epsilon) < 12). Silicon-on-sapphire (SOS) substrates have acceptably low dielectric constants and provide other import
