This review presents an overview of the thermal properties of mesoscopic structures. The discussion is based on the concept of electron energy distribution, and, in particular, on controlling and probing it. The temperature of an electron gas is determined by this distribution: refrigeration is equivalent to narrowing it, and thermometry is probing its convolution with a function characterizing the measuring device. Temperature exists, strictly speaking, only in quasiequilibrium in which the distribution follows the Fermi-Dirac form. Interesting nonequilibrium deviations can occur due to slow relaxation rates of the electrons, e.g., among themselves or with lattice phonons. Observation and applications of nonequilibrium phenomena are also discussed. The focus in this paper is at low temperatures, primarily below 4 K, where physical phenomena on mesoscopic scales and hybrid combinations of various types of materials, e.g., superconductors, normal metals, insulators, and doped semiconductors, open up a rich variety of device concepts. This review starts with an introduction to theoretical concepts and experimental results on thermal properties of mesoscopic structures. Then thermometry and refrigeration are examined with an emphasis on experiments. An immediate application of solid-state refrigeration and thermometry is in ultrasensitive radiation detection, which is discussed in depth. This review concludes with a summary of pertinent fabrication methods of presented devices.

“…The idea of the Andreev receiver was intensely developed in the 1990s and was one of the most promising concepts for astronomical research at that time. However, it was shown in [55] that the DC measured noise-equivalent power is 5 • 10 −18 W/GHz 1/2 and deteriorates significantly (up to 10 −14 W/GHz 1/2 ) during irradiation by a 300 GHz signal and the volt-watt sensitivity drops to 10 6 V/W. This impairment of the main characteristics of the receiver when exposed to an external signal is explained by the fact that at a frequency higher than the energy gap of the superconductor (i. e., more than 70 GHz for aluminum) the superconductor -normal-metal contacts become "transparent" to radiation.…”

“…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.
