The discovery of hot-electron phenomena in a thin superconducting film in the last century
was followed by numerous experimental studies of its appearance in different materials …

Jacket illustration. CryoSEM micrograph of a freeze-fractured yeast cell. Specimen was
prepared according to Walther et al (1995) and imaged using back-scattered electrons …

This paper reviews progress in superconductor electronics over the decade since the
discovery of the high temperature oxide superconductors (HTS). Almost simultaneously with …

We report a systematic, comprehensive set of measurements on the dynamics and noise
processes in diffusion and phonon-cooled superconducting hot-electron bolometer mixers …

The generation of continuous-wave (CW) terahertz radiation by the photomixing (optical
heterodyne downconversion) with the ultrafast optoelectronic devices is reviewed. The …

A photomixer local oscillator (LO) operating at the 630-GHz difference frequency of two laser
diodes was successfully demonstrated with a heterodyne detector based on a niobium …

In this paper, an analysis of parasitic elements that are found in all typical metal-oxide-
semiconductor field-effect transistors (MOSFETs) has been performed from a viewpoint of a …

We report on the development of terahertz broadband detectors utilizing superconducting
hot-electron bolometers and planar sinuous antennas. In this work, sinuous antennas …

We measure the direct response of a Nb diffusion-cooled hot-electron bolometer mixer in a
frequency range between 0.5 and 3.5 THz. The mixer consists essentially of a twin-slot …

Diffusion-cooled Nb hot-electron bolometer (HEB) mixers have the potential to
simultaneously achieve high intermediate frequency (IF) bandwidths and low mixer noise …
