The interest in 2D layered materials based short wavelength infrared (SWIR) photodetectors (PDs) has escalated over the years with the introduction of new 2D materials showing intriguing photoresponse characteristics in the IR region. 2D materials with their mechanical flexibility, bandgap tunability, ease in exfoliation and thickness dependent optical properties have shown the potential to surpass the performance of conventional, cryogenically operated semiconducting PDs. To date, a significant number of PDs have been reported using layered materials in various configurations, which has attracted the interest of research community towards scalable 2D-PDs. This review article aims to address the current state-of-art SWIR PDs based on layered materials and the underlying physics. The article gives an insight into the various photodetection schemes and the important figure of merits for the evaluation of PDs. The 2D materials frequently employed for the design of SWIR PDs and their important characteristics are discussed in detail, with special emphasis on their photodetection range. Further, a comprehensive review of the 2D SWIR PDs based on different device structures is included, followed by a discussion on the major challenges currently prevalent in 2D SWIR PDs. Finally, the promising future prospects of 2D SWIR PDs and their important applications are described.

“…A single response and recovery curve of the photodetector at on and off states with an effective light power of 6.6 mW cm –2 is shown in Figure d, which reveals that the response time (τ res ) and recovery time (τ rec ) of the photodetector are 115 and 121 ms, respectively. The device shows good performance among previously reported 2D-material-based Schottky contacted photodetectors (Table S2), which indicates great potential of borophane for further study and application in nanoelectronics and nanophotonics. ,− …”

Borophene has drawn tremendous attention in the past decade for a wide range of potential applications owing to its unique structural, optical, and electronic properties. However, applications of borophene toward next-generation nanodevices are mostly theoretical predictions, while experimental realization is still lacking due to rapid oxidation of intrinsic borophene in an air environment. Here, we have successfully prepared structurally stable and transferrable few-layer β 12 -borophane on copper foils by a typical two-zone chemical vapor deposition method, where bis(triphenylphosphine)copper tetrahydroborate was used as the boron source in a hydrogen-rich atmosphere to stabilize its structure through hydrogenation. The crystal structure of the as-prepared β 12borophane is in good agreement with previous reports. A fabricated photodetector based on β 12 -borophane−silicon (n-type) Schottky junction shows good photoelectric responses to light excitations in a wide wavelength range from 365 to 850 nm. Especially, the photodetector exhibits a good photoresponsivity of around 0.48 A W −1 , a high specific detectivity of 4.39 × 10 11 jones, a high external quantum efficiency of 162%, and short response and recovery times of 115 and 121 ms under an ultraviolet light with the wavelength of 365 nm at a reverse bias of 5 V. The results show great potential applications of borophane in nextgeneration nanophotonic and nanoelectronic devices.
