Flexible photodetector based on large-area few-layer MoS2

Thermal properties of thin films made from MoS2 nanoflakes and probed via statistical optothermal Raman method

“…Mechanical exfoliation was applied to the layered structure of this material in order to isolate the first single-layer two dimensional (2D) semiconductor 2 . Over the years, various MoS 2 properties have been exploited for a wide range of applications from electronic and optoelectronic devices such as transistors 3,4 , photodetectors 5,6 , and even integrated circuits 7 to hydrogen production systems 8 and lithium batteries 9 . Depending on the intended application, one can choose from several 2D molybdenum disulphide production methods 2,10–12 .…”

Low dimensional freestanding semiconductors for flexible optoelectronics: materials, synthesis, process, and applications

“…This photodetector is sensitive over a broad range from 370 to 1064 nm with a peak responsivity of 0.92 A/W at 635 nm, which only decreases by 5% at a bending radius of 5 mm [96]. Similar TMD photodetectors with MoS 2 nanosheets on PET are also possible, with thicknesses of 1-5 nm [97] which is much thinner than for the previous device. This flexible photodetector indicates a responsivity of 0.02 A/W, similar to other MoS 2 photodetectors [97].…”

This flexible photodetector indicates a responsivity of 0.02 A/W, similar to other MoS 2 photodetectors [97]. Figure 13(h) shows a flexible photodetector with TMDs such as MoS 2 , MoSe 2 , WS 2 , and WSe 2 hybridized with amine-terminated polymers polystyrene (PS), poly(methyl methacrylate) (PMMA), poly(butadiene) (PBd), poly(ethylene) (PE), poly(ethylene oxide) (PEO), and poly(styrene-b-iso prene) (Ps-b-PI).…”

The highly-efficient light-emitting diodes based on transition metal dichalcogenides: from architecture to performance

“…Furthermore, exible devices are expected to meet the increasing demands for wearable and portable electronics. MoS 2 -dependent exible optoelectronic devices have been fabricated, [119][120][121][122] so it may be interesting to prepare exible LEDs based on TMDCs. MoS 2 with piezo-phototronic effects has been fabricated, which indicates a new direction for the study of other TMDC piezo-phototronic devices.…”
