Abstract: | 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. |
