Terahertz (THz) technology is one of emerging technologies that will change our life. A lot of attractive applications in security, medicine, biology, astronomy, and non-destructive materials testing have been demonstrated already. However, the realization of THz emitters and receivers is a challenge because the frequencies are too high for conventional electronics and the photon energies are too small for classical optics. As a result, THz radiation is resistant to the techniques commonly employed in these well established neighbouring bands.In the paper, issues associated with the development and exploitation of THz radiation detectors and focal plane arrays are discussed. Historical impressive progress in THz detector sensitivity in a period of more than half century is analyzed. More attention is put on the basic physical phenomena and the recent progress in both direct and heterodyne detectors. After short description of general classification of THz detectors, more details concern Schottky barrier diodes, pair braking detectors, hot electron mixers and field-effect transistor detectors, where links between THz devices and modern technologies such as micromachining are underlined. Also, the operational conditions of THz detectors and their upper performance limits are reviewed. Finally, recent advances in novel nanoelectronic materials and technologies are described. It is expected that applications of nanoscale materials and devices will open the door for further performance improvement in THz detectors.

“…The spectroradiometer uses a low-noise superheterodyne receiver with an SBD mixer, which is similar to that described earlier in [5]. A broadband mixer and an intermediate-frequency preamplifier (IFPA) based on pHEMT transistors with high mobility of carriers [6] are combined into a single block [7].…”

We developed a high-sensitivity receiving and measuring facility designed for observations of the ozone O 3 and carbon monoxide CO spectral lines by the method of ground-based remote sensing of the atmosphere in the 90-116 GHz frequency range. The measurement and calibration procedure is described in detail. The results of observations of the O 3 and CO emission lines at frequencies 110.836 amd 115.271 GHz, respectively, are presented. The sensitivity level of the receiving and measuring facility, which was implemented in the experiment using a filter-bank analyzer and a Fourier spectrum analyzer is determined.

“…One of the most sensitive SBD planar mixer receivers at n = 100 GHz and room tempera− ture operation and at T = 20 K were reported in Ref. 85. It was cited that the noise temperature is T noise (300 K) = 200 K and T noise (20 K) = 55 K, respectively.…”

In the paper, issues associated with the development and exploitation of terahertz (THz) radiation detectors are discussed. The paper is written for those readers who desire an analysis of the latest developments in different type of THz radiation sensors (detectors), which play an increasing role in different areas of human activity (e.g., security, biological, drugs and explosions detection, imaging, astronomy applications, etc.). The basic physical phenomena and the recent progress in both direct and heterodyne detectors are discussed. More details concern Schottky barrier diodes, pair braking detectors, hot electron mixers, and field-effect transistor detectors. Also the operational conditions of THz detectors and their upper performance limits are discussed.
