Near-infrared photodetector based on few-layer MoS2 with sensitivity enhanced by localized surface plasmon resonance

Two-dimensional layered molybdenum disulfide (MoS2) exhibits great potential for applications in optoelectronic devices, especially photodetectors. However, most of the reported MoS2-based photodetectors only show limited absorption in visible range, resulting in narrow spectral response with poor sensitivity. Integrating plasmonic nanoparticles with MoS2 provides a promising approach to enhance light-matter interactions and detector responsibility. We here report a plasmon-enhanced photodetector based on Au/MoS2 heterostructure with Au nanoparticles (NPs) deposited on the surface of few-layer MoS2 by magnetron sputtering. By coupling with Au NPs, the interactions between ultra-thin MoS2 and incident lights are greatly enhanced via localized surface plasmon resonance. With this new architecture, the spectral response of few-layer MoS2 based photodetector is extended to near-infrared region (700–1600?nm). Further, measurements show that significant improvement of photocurrent is observed with the highest value reaching up to 64?mAW?1 at incident wavelength of 980?nm. With the demonstrated superb performance the proposed detector represents a viable path towards implementing ultra-sensitive near-infrared detection.
