Ⅲ.阵列结构中的红外探测器红外探测器用于将入射的辐射能量,直接或间接地转换为电信号。我们将主要讨论所谓光子探测器的这一类器件,它通过光致激发在半导体中把光子直接转换为自由载流子。第二类是热探测器。在这种探测器中,被晶格吸收的入射辐射能量提高了晶格的温度,并随之改变了探测器的电子特性。热探测器的灵敏度大大低于光子探测器的灵敏度,但它的优点是能在室温下工作。按照本 III. INFRARED DETECTORS IN ARRAYS Infrared detectors are used to directly or indirectly convert incident radiant energy into electrical signals. We will focus on this type of device called photon detectors, which convert photons directly into free carriers in semiconductors by photo-excitation. The second category is the heat detector. In this detector, the energy of the incident radiation absorbed by the lattice increases the temperature of the lattice and, in turn, changes the detector’s electronic properties. Thermal detectors are significantly less sensitive than photodetectors but have the advantage of being able to operate at room temperature. Follow this
