Abstract
Due to its diverse crystal configurations with varying bandgaps, Silicon Carbide (SiC) has been widely utilized by numerous researchers in the preparation of photodetectors. In this paper, we propose high performance tunable photodetector with graphene-based SiC grating structure. The photodetector can achieve perfect absorption and the responsivity of 10.61 A/W at 11.7 μm wavelength. The tunable broadband photodetection from 11.4 μm to 12 μm can be obtained by adjust graphene’s Fermi level. Compared with existing graphene-based photodetector with or without SiC structures, our structure has more flexible detection and higher performance. In addition, we explain the standing wave phenomenon observed during the tuning of the photodetector structure. This provides a new direction for the development of high-quality infrared photodetectors.
期刊介绍：
This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
