Design and Fabrication of Hybrid Nanowire Graphene Photodetectors

EasyChair Preprint 14384

Abstract

In recent years, the development of advanced photodetectors has gained significant attention due to their crucial role in various optoelectronic applications. This paper explores the design and fabrication of hybrid photodetectors that integrate nanowires and graphene, aiming to leverage the unique properties of both materials to enhance device performance. Nanowires, known for their high surface area and tunable electronic properties, are combined with graphene’s exceptional electron mobility and broad optical absorption spectrum to create photodetectors with improved sensitivity and response time.

The design considerations include the selection of appropriate nanowire and graphene materials, as well as the optimization of device architecture to maximize performance. Various fabrication techniques, such as chemical vapor deposition for nanowires and mechanical exfoliation or chemical vapor deposition for graphene, are employed to achieve high-quality components and effective integration. The resulting hybrid photodetectors are characterized through structural analysis, electrical measurements, and optical testing to evaluate their performance metrics, including responsivity, sensitivity, and response time.

Results demonstrate that the hybrid nanowire/graphene photodetectors offer superior performance compared to traditional devices, highlighting their potential for applications in high-speed telecommunications, imaging systems, and other advanced optoelectronic technologies. This work provides a comprehensive approach to the design and fabrication of these hybrid devices and outlines future research directions to further enhance their capabilities and broaden their application scope.
