(author), Klapwijk, T.M. (author)We present a physically consistent interpretation of the dc electrical properties of niobiumnitride (NbN)-based superconducting hot-electron bolometer mixers, using concepts of nonequilibrium superconductivity. Through this, we clarify what physical information can be extracted from the resistive transition and the dc current-voltage...journal article 2016

(author), Voronov, B.M. (author), Rodin, A. (author), Klapwijk, T.M. (author), Gol'tsman, G.N. (author)We report on design and characterization of a superconducting Hot Electron Bolometer Mixer integrated with a logarithmic spiral antenna for mid-IR range observations. The antenna parameters have been adjusted to achieve the ultimate performance at 10 ?m (30 THz) range where O3, NH3, CO2, CH4, N2O, . lines in the Earth’s atmosphere, in planetary...conference paper 2015

(author), Presniakov, M. (author), Bobrinetskiy, I. (author), Ibragimov, R. (author), Goltsman, G. (author)We report on the voltage response of carbon nanotube devices to sub-terahertz (THz) radiation. The devices contain carbon nanotubes (CNTs), which are over their length partially suspended and partially Van der Waals bonded to a SiO2 substrate, causing a difference in thermal contact. We observe a DC voltage upon exposure to 140?GHz radiation....journal article 2013
