“…Normal metal-insulator-superconductors (NISs), as well as SIS tunnel junctions, are the main building blocks in superconducting electronics. SINIS is one of the generic elements of a wide family of cryogenic devices [1][2][3], such as Andreev bolometers (AB) [4,5], normal metal hot-electron bolometers (NHEB) [6], cold-electron bolometers (CEB) [7,8], SINIS bolometers [9][10][11], SINIS detectors [12][13][14], NIS array thermometers [15][16][17], electron coolers [18][19][20][21], and photon counters. Over the 30 years in which they have been in development, detectors with NIS tunnel junctions have been referred to as ANHEBa normal metal hot-electron bolometer with Andreev reflection (SNS + NIS), actually operating at frequencies below 70 GHz; CCNHEB [22]-capacitive coupled normal metal hot-electron bolometers (SINIS); CEB-cold-electron bolometers (SINIS), which are the same as CCNHEB, but operate with electron cooling; SINIS detectors-an SINIS structure in the operation mode of quantum response, at frequencies above 70 GHz; an NISIN detector with a structure similar to SINIS, or even NININ or MIMIM detectors with metal-insulatormetal tunnel junctions [23,24].…”

This review presents the main characteristics and mechanisms of operation of superconductor–insulator–normal metal–insulator–superconductor (SINIS) microwave detectors. An analysis of the detectors’ performance against a quantum detector and a photon counter is given. Methods for cooling a superconductor using normal metal traps and the role of electron cooling in optimizing the current response to terahertz radiation are discussed. Fabrication methods using shadow evaporation as well as magnetron sputtering are described.

“…As a broadband direct detector, the authors study sensitive elements based on superconductorinsulator -normal metal -insulator -superconductor structures. In a broad sense, the term "SINIS structures" includes many devices [43][44][45] ranging from thermometers [46][47][48] and electronic coolers [49][50][51][52] to various detectors, such as the Andreev bolometer [53][54][55], a cold-electron bolometer [56-57], SINIS bolometers [58,59], SINIS detectors [60,61], and SINIS detectors with a suspended absorber and a high quantum efficiency [62,63].…”

We give a review of both our own original scientific results of the development of superconducting receivers for sub-terahertz astronomy and the main leading concepts of the global instrumentation. The analysis of current astronomical problems, the results of microwave astroclimate research, and the development of equipment for sub-terahertz radio astronomy studies justify the need and feasibility of a major infrastructure project in Russia to create a sub-terahertz telescope, as well as to enhance the implementation of the ongoing Millimetron and Suffa projects. The following results are discussed: i) superconducting coherent receivers and broadband subterahertz detectors for space, balloon, and ground-based radio telescopes have been developed and tested; ii) ultrasensitive receiving systems based on tunnel structures such as superconductorinsulator -superconductor (SIS) and superconductor -insulator -normal metal -insulatorsuperconductor (SINIS) have been created, fabricated, and examined; iii) a receiving array based on SINIS detectors and microwave readout system for such structures has been implemented; iv) methods for manufacturing high-quality tunnel structures Nb/AlO x /Nb and Nb/AlN/NbN based on niobium films with a current density of up to 30 kA/cm 2 have been developed. Receivers operated at 200 to 950 GHz and having a noise temperature only a factor of 2 to 5 higher than the quantum limit have been created and tested.

“…Such a device has strong temperature-dependent current-voltage characteristics, submicron size, low self heating and natural bandwidth up to few MHz [4], and has been used extensively in studies of low-temperature thermal transport [5][6][7]. It is also an attractive candidate for far-infrared bolometry applications [8].…”

We have studied an inductive readout for normal metal-insulator-superconductor (NIS) tunnel junctions by using on-chip planar inductors and a DC SQUID (superconducting quantum interference device) to develop a sensitive and fast thermometer for studies of nanoscale heat conduction and bolometry. Our initial results show the feasibility of the concept, with a good sensitivity for temperatures below 1 K for aluminum as the superconductor when voltage biased close to the superconductor energy gap.
