Quantum-amplified p-type quantum well infrared detector

Abstract

The invention provides a quantum-amplified p-type quantum well infrared detector, and belongs to the technical field of infrared detectors, the quantum-amplified p-type quantum well infrared detector comprises a fixed plate and a protective cover body, the upper surface of the fixed plate is provided with a detector main body, one side of the detector main body is fixedly connected with a fixed ring, and the fixed ring is fixedly connected with the protective cover body. The inner top wall of the protective cover body is fixedly connected with an insulating plate, and one side face of the insulating plate is fixedly connected with a sealing clamping strip. After detection is completed, the protective cover body is locked on the fixing plate, the sealing clamping strip can be inserted into the sealing groove in a sealed mode in the process, the protective cover body and the fixing plate can be connected in a sealed mode, external dust is prevented from entering the interior of the detector body, and then certain insulation protection can be achieved on the detector body through the insulation plate. And external current is prevented from damaging components in the detector main body, so that the device has relatively high self-protection performance, and the service life of the device is indirectly prolonged.

Description

technical field [0001] The invention belongs to the technical field of infrared detectors, in particular to a p-type quantum well infrared detector with quantum amplification. Background technique [0002] Infrared detectors can be used to determine whether there are modulated infrared rays emitted by hand-held remote controls nearby. Infrared detection is a specialized technology that uses the principle of infrared radiation to inspect and measure the surface of equipment or materials and other objects. At present, with the continuous advancement of science and technology, more and more advanced infrared detectors appear in all walks of life, such as p-type quantum well infrared detectors, which have large detection area, high imaging efficiency and fast response speed Etc. However, due to the poor self-protection of the current general quantum well infrared detectors, it is easy to be damaged by external factors, which reduces the service life of electrical equipment, and...
