Abstract

The invention discloses a three-color detector and a manufacturing method thereof. The three-color detector comprises: a GaN substrate arranged sequentially; an AlGaN sub-detector arranged between the AlGaN sub-detector and the GaN substrate There is a first buffer layer; the InGaAs sub-detector is connected to the AlGaN sub-detector through a bonding layer; the InGaNAs sub-detector is provided with a tunnel junction between the InGaAs sub-detector, and the InGaNAs sub-detector The detector is provided with a second buffer layer. By vertically integrating the detection structure of multiple bands of ultraviolet / visible light / infrared in the depth direction, the GaN material is used to respond to the ultraviolet band information of <365nm, the InGaAs material is used to respond to the 365~1700nm band information, and the InGaNAs material is used to respond to the mid-infrared band of 1700~3000nm information, realize simultaneous detection of ultraviolet / visible light / infrared bands, obtain "color" images of targets, and obtain target information more abundantly, accurately and reliably.

Description

technical field [0001] The invention relates to the field of photoelectric detectors, in particular to a three-color detector and a manufacturing method thereof. Background technique [0002] The principle of a photodetector is that radiation causes a change in the conductivity of the irradiated material. Photodetectors are widely used in various fields of military and national economy. Among them, infrared detectors are the most typical, and are widely used in weather and meteorological forecasting, satellite exploration and monitoring of earth resources, spectral analysis of ground features and landscapes, and crops. Existing infrared detectors are only effective for light waves in the infrared band, and can only The monochromatic "black and white" photos of the target are obtained, and the information of the target is very limited, which cannot accurately reflect the accurate information of the detected target. Contents of the invention [0003] The present invention ...
