Pentin IV, Smirnov AV, Ryabchun SA, Ozhegov RV, Gol’tsman GN, Vaks VL, et al. Semiconducting superlattice as a solid-state terahertz local oscillator for NbN hot-electron bolometer mixers. Tech Phys. 2012;57(7):971–4. Abstract: We present the results of our studies of the semiconducting superlattice (SSL) frequency multiplier and its application as part of the solid state local oscillator (LO) in the terahertz heterodyne receiver based on a NbN hot-electron bolometer (HEB) mixer. We show that the SSL output power level increases as the ambient temperature is lowered to 4.2 K, the standard HEB operation temperature.

Smirnov AV, Karmantsov MS, Smirnov KV, Vakhtomin YB, Masterov DV, Tarkhov MA, et al. Terahertz response of thin-film YBCO bolometers. Tech Phys. 2012;57(12):1716–9. Abstract: The bolometric response of high-temperature thin-film YBCO superconducting detectors to an electromagnetic radiation with a frequency of 2.5 THz is measured for the first time. The minimum value of the noise-equivalent power of the detectors is 3.5 × 10−9 W/Hz−−−√. The feasibility of further increasing the sensitivity of the detectors is discussed.
