High-operating-temperature Infrared Photodetectors illustrated Edition [Mīkstie vāki]

Cryogenic cooling has always been a challenging part of sensitive infrared (IR) systems, adding weight, size, cost, power consumption and inconvenience to what is otherwise an efficient and efficacious design. Concentrating on the latest developments for efficiently cooling detectors that operate in the middle- and long-wavelength IR spectrum, practitioner Piotrowski and Rogalski (applied physics, Military U, of Technology, Warsaw) describe innovations in the cooling of many types of IR photodetectors with emphasis on HgCdTe alloy based detectors. They describe the fundamental performance limitations of IR photodetectors, materials used for and the operation of intrinsic photodetectors, and applications to a range of devices including photoconductors, photoelectromagnetic and Denber effect detectors and photodiodes. They include commentary on the innovations to date and a summary of what we can expect shortly. Although written primarily for graduate students, this can also serve as a reference for practitioners.
