Synergistic Effects of Plasmonic Au Nanoislands on a MoSe2 Nanoflake/ZnO Nanorod Heterostructure for an Enhanced Broadband Photoresponse

“…Boosting of light-trapping capabilities based on these nanostructures through light–matter interactions is essential for their use in device applications. Arrays of 1D nanostructures like nanocones or nanorods (NRs) and their contribution in a higher photoresponse have been proven to be effective and useful for future transparent and flexible nanodevices. − In this regard, zinc oxide (ZnO) nanostructures are important because of their high band gap, chemical stability, and optical transparency. , Combination of these nanostructures with atomically thin 2D TMDs like MoS 2 , and WS 2 , has been reported to provide improved performance in terms of sensitivity with additional light absorption capability and broadening of the spectral range. On the other hand, the large surface area of 1D or 2D materials and the coupling of their excitonic features with metal nanoparticle (NP)-induced plasmonic interactions have shown promising opportunities in realizing fast and efficient devices. − Metal NPs through localized surface plasmon resonance (LSPR) can trap light on the surface of a material by strongly controlling the absorption and emission spectra and depending on the shape and morphology of the metal NPs, such physical effects can be tuned to a great extent in terms of coupling strength. ,− Integration of stable plasmonic metal NPs like gold (Au) has been especially useful for photovoltaics and broadband photodetection. − However, the fabrication of such mixed-dimensional devices is challenging in terms of growth of thin-layered (2D) materials on top of the large-area vertical (1D) micro/nanostructures.…”

Self-assembled graphene/BUBD-1 hybrids for ultrasensitive organic phototransistors

“…Even so, the value of D* could reach up to 410 11 cm Hz 1/2 W À1 under all gate voltages. To benchmark our device, we compared graphene-based high-performance hybrid phototransistors using various strategies, including charge-transfer assistance, 8,10,28,[37][38][39][40][41] substrate engineering, [42][43][44] tunneling assistance, [45][46][47] a vertical structure, 48,49 and contact engineering, 5,50,51 as summarized in Fig. 5d.…”

The Quantum Internet: A Hardware Review

“…However, there are methods to work around this problem, such as the stretchable solution presented by Kang et al 43 . Zhuo et al have demonstrated a graphene-based photodetector that integrates multiple fibers, including carbon nanotubes (CNTs), resulting in increased responsivity 44 .…”
