| titleOfInvention | Infrared detector and preparation method thereof |
| abstract | The invention discloses an infrared detector and a preparation method thereof, wherein the infrared detector comprises: the metal electrode, and the substrate, the gallium arsenide substrate and the graphene layer which are arranged from bottom to top in sequence; the substrate is provided with a strip array groove parallel to the gallium arsenide base layer, the gallium arsenide base layer is arranged on the strip array groove, the surface of the gallium arsenide base layer is provided with indium arsenide quantum dots, and the metal electrodes are arranged at two ends of the gallium arsenide base layer. According to the invention, the indium arsenide quantum dots are arranged on the surface of the gallium arsenide base layer, and meanwhile, the gallium arsenide base layer can grow transversely relative to the strip array-type groove, so that the photoresponse capability of the gallium arsenide base layer can be improved, the response time of the infrared detector is shortened, the extraction efficiency of photo-generated carriers can be improved through the matching among the graphene layer, the gallium arsenide base layer and the metal electrode, and the sensitivity of the infrared detector is improved. |
