A novel flexible broadband photodetector based on flower-like MoS2 microspheres

A review of molybdenum disulfide (MoS2) based photodetectors: from ultra-broadband, self-powered to flexible devices

“…Tremendous interest is growing in the eld of MoS 2 based photodetectors as new research ideas are emerging on a rapid pace. [383][384][385][386][387] Ahmed et al 388 fabricated graphene/h-BN/MoS 2 trilayer vdW heterostructure-based phototransistors to examine the photogating mechanism where h-BN layer was used as an interfacial barrier to monitor the charge transfer process. Mechanically exfoliated monolayer graphene, MoS 2 and multilayer h-BN were used to fabricate the graphene/h-BN/MoS 2 vdW heterostructures on the SiO 2 /(p ++ )-Si substrate.…”

Improving Photoelectric Conversion with Broadband Perovskite Metasurface

“…(iv) The response time is shorter than 5.1 μs at three different wavelengths, which corresponds to a 3 dB bandwidth higher than 0.26 MHz. Such response time is shorter than those of the detectors − in Table . The rapid response of the device at different wavelengths demonstrates its potential for high-speed detection in the ultraviolet and visible spectra and broadband optical communications.…”

Flexible electronics based on 2D transition metal dichalcogenides

“…In another case, a thin-lm photodetector based on MoS 2 nano-owers was fabricated. 222 The high specic area of MoS 2 nano-owers enhances the effective area of the channel and improves the device sensitivity. The device can show fast responses in the entire visible light range and barely present degradation under bending at 0.75 cm.…”
