Semiconductors for low energies: incoherent infrared/sub-millimetre detectors

  • Walfried Raab
Part of the ISSI Scientific Report Series book series (ISSI, volume 9)


Semiconductor-based detectors have been used to detect infrared radiation since the early days of space astronomy, and are now the workhorse of infrared space missions. Whilst their leading position in space applications is starting to be challenged by the promise of large-format, high-performance bolometer arrays, semiconductor devices are currently the most sensitive detector type at infrared wavelengths and will undoubtedly continue to play an important role. This chapter gives an overview of the state-of-the-art semiconductor-based detector types and the materials commonly used to cover the different wavelengths, providing insight into the key performance parameters and system trade-offs. Important considerations for the operation of semiconductor-based detectors and the most common read-out techniques and interconnection schemes used are also discussed. The chapter is rounded off by a brief overview of the most promising technologies currently under development in this waveband.
