TL;DR: A high-performance gas sensor constructed using atomic-layered MoS2 synthesised by chemical vapour deposition (CVD) was developed and the in situ PL characterisation of the changes in the peaks corresponding to charged trions and neutral excitons via gas adsorption processes was used to elucidate the mechanisms of charge transfer between theMoS2 and the gas molecules.

TL;DR: Several applications of graphene films as electrodes in electrical and optical devices are reviewed and the essential requirements are discussed, which include low sheet resistance, high optical transparency and excellent mechanical properties.

TL;DR: This work demonstrates a large-scale batch fabrication of GaN light-emitting diodes (LEDs) with patterned multi-layer graphene (MLG) as transparent conducting electrodes as a potential development toward future practical application of graphene electrodes in optoelectronic devices.

TL;DR: A bifunctional sensor within a single MoS2 device to detect photons and gas molecules in sequence is finally demonstrated, paving a way toward a versatile sensing platform for a futuristic multifunctional sensors.

TL;DR: There was no substantial variation observed in the current levels of the WORM memory devices upon bending and bending cycling up to 10 000 times, and a retention time of over 10(4) s was observed without fluctuation under bending.
