Infrared and terahertz detectors This new edition of Infrared and Terahertz Detectors provides a comprehensive overview of infrared and terahertz detector technology from fundamental science to materials and fabrication techniques. It contains a complete overhaul of the contents including several new chapters and a new section on terahertz detectors and systems. It includes a new tutorial introduction to technical aspects that are fundamental for basic understanding. The other dedicated sections focus on thermal detectors photon detectors and focal plane arrays Radiometry Infrared systems fundamentals Infrared detector characterization Fundamental performance limitations of infrared detectors Coupling of infrared radiation with detector Heterodyne detection Thermopiles Bolometers Pyroelectric detectors Pneumatic detectors Novel thermal detectors Theory of photon detectors Intrinsic silicon and germanium detectors Extrinsic silicon and germanium detectors Photoemissive detectors III V detectors HgCdTe detectors IV VI detectors Quantum well infrared photodetectors Superlattice photovoltaic detectors Quantum dot infrared photodetectors Infrared barrier photodetectors Cascade infrared photodetectors Overview of focal plane array architectures Thermal detector focal plane arrays Photon detector focal plane arrays Third generation infrared detectors Terahertz detectors and focal plane arrays
