A kind of photodetector and preparation method based on carbon quantum dots and graphene |
| abstract |
The invention discloses a photodetector based on carbon quantum dots and graphene and a preparation method. The photodetector comprises a silicon substrate, a graphene film, a carbon quantum dot and a source-drain electrode. The photodetector of carbon quantum dots and graphene provided by the present invention uses carbon quantum dots as a light absorbing medium layer to realize the conversion of photoelectric signals; uses graphene as a transmission material to realize rapid transport of carriers; The carbon quantum dots on the graphene film have an adjustable band gap and can interact with the graphene, so that the photogenerated carriers can be effectively separated and transported rapidly, and the responsivity of the detector is improved; the preparation process of the invention is simple, the cost is low, and the It has the characteristics of controllable structure, easy integration and high responsiveness. |
