Electron-phonon relaxation in hot-electron detectors below 1 K
Recently proposed submillimeter hot-electron direct detecors based on normal metals and superconductors rely on the thermal coupling between electrons and phonons. The sensitivity of the detectors can be greatly enhanced if the coupling is made very weak at subkelvin temperatures.

Novel multiplexing technique for detector and mixer arrays
Future space submillimeter telescopes will require large-format imaging detector arrays to perform state-of-the-art astronomical observations. A crucial issue related to a focal plane array is a readout scheme which is combatible with large numbers of cryogenic detectors elements.

Photon-Noise Limited Direct Detector Based on Disorder-Controlled Electron Heating
We present a new concept for a hot-electron direct detector (HEDD) capable of counting single millimeter-wave photons. The detector is based on a transition edge sensor (1-meu size bridge) made form a disordered superconducting film.

Noise and Bandwidth Measurements of Diffusion-Cooled Nb Hot-Electron Bolometer Mixers at Frequencies Above the Superconductive Energy Gap
Diffusion-cooled Nb hot-electron bolometer (HEB) mixers have the potential to simultaneously achieve high intermediate frequency (IF) bandwidths and low mixer noise temperatures for operation at THz frequencies (above the superconductive gap energy).
