Molybdenum disulfide plasmonic heterostructures

Similarly, the photoresponsivity of 59.60 A W−1 and detectivity of 4.51 × 1010 Jones for the 1L MoS2/AgNW hybrid photodetector were 1000 times enhanced compared to those of the pristine 1L-MoS2 photodetector (0.05 A W−1 and 4.11 × 107 Jones). The significant improvement in the optoelectronic properties of the 1L MoS2/AgNW hybrid photodetector occurred due to the surface plasmon coupling of the AgNW network. In another study, Jing et al. enhanced the localized surface plasmon resonance (LSPR) by depositing Ag nanoparticles onto monolayer MoS2 for developing phototransistors. AgNPs/MoS2 hybrid-based phototransistors showed a 470% increase in photoresponsivity, changing from 5.35 × 103 A W−1 to 2.97 × 104 A W−1 at 610 nm for 25 nm AgNPs. The interactions between MoS2 layers and light are enhanced by the integrated Au or Ag nanostructures due to the LSPR, which significantly improves the photoresponse of plasmon heterostructure-based hybrid MoS2 photodetectors. Sun et al. used silica layer-coated silver nanocubes (AgNCs) with optimized LSP in the gap mode for developing a flexible MoS2 photodetector. The PL spectrum of the MoS2/Ag nanocubes hybrid was significantly enhanced compared with MoS2 film after modifying Ag NCs with underneath Ag thin film due to interactions between the MoS2 excitons and LSP in the gap mode.  compares the photoresponsivity and photocurrent of MoS2 and flexible MoS2/Ag nanocubes (NCs) hybrid-based photodetectors as a function of incident laser power and time, respectively. Photocurrent rise (τrise) and decay (τdecay) times and flexible MoS2/AgNCs hybrid-based photodetector mechanical stability are also depicted. The photocurrents of the photodetectors fabricated using pristine MoS2 film and MoS2 film with underneath Ag film were almost the same (48–50 nA) at 3 V under 520 nm laser illumination with 46 nW incident power. In contrast, the photocurrent of flexible photodetector having MoS2 film in the gap of the Ag layer and AgNCs was considerably increased to 0.91 μA under similar experimental conditions due to the Ag nanocubes.
