Abstract

Two-dimensional graphene (2-D graphene) has limited application potential in optoelectronics because of its low light absorptivity and gapless property. This work presents photodetectors with increased light absorption efficiency, which couple 3-D graphene with the optical cavity structure of germanium-on-insulator (GeOI). Multiple reflections are generated at the 3-D graphene/GeOI heterojunction due to the unique plasmonic nanoresonator and optical cavity structures. The photodetectors exhibit excellent responsivity (R=0.9×104 mAW-1) and specific detectivity (D∗ = 3.96×1010cmHz1/2W-1) under 1550-nm illumination with fast response rates, excellent reproducibility, and long-Term stability. The technique paves the way for creating novel high-performance graphene-based photodetectors with hybrid architectures.
