  • INGAN/GAN MULTIPLE QUANTUM WELL BLUE LIGHT DETECTOR COMBINED WITH EMBEDDED ELECTRODE AND PASSIVATION LAYER STRUCTURE AND PREPARATION METHOD AND APPLICATION THEREOF
    Publication number: 20220328706
    Abstract: An InGaN/GaN multiple quantum well blue light detector combined with embedded electrode and passivation layer structure and a preparation method and an application thereof are provided. The detector includes: a Si substrate, an AlN/AlGaN/GaN buffer layer, a u-GaN/AlN/u-GaN/SiNx/u-GaN buffer layer, an n-GaN buffer layer, an InGaN/GaN superlattice layer and an InGaN/GaN multiple quantum well layer in sequence from bottom to top. The multiple quantum well layer has a groove structure, a mesa and a groove of the multiple quantum well layer are provided with a Si3N4 passivation layer. The passivation layer in the groove is provided with a first metal layer electrode with a semicircular cross section, and the passivation layer on the mesa is provided with second metal layer electrode.
