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: 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: In this paper, a short pulse current-voltage method was used to identify trap time constants around 87μs and 1.76 ms with reversible trapping behavior of graphene field effect transistors.

TL;DR: The palladium-decorated graphene nanoribbons array exhibited a rectangular sensing curve with unprecedented rapid response and recovery properties and reliable and repeatable sensing behaviors were revealed when the array was exposed to various gas concentrations even at 30 ppm.

TL;DR: The benefits of multi-layer graphene (MLG) capping on Cu interconnects have been experimentally demonstrated, suggesting that the MLG can act as an excellent capping material for Cu interConnects, improving the reliability characteristics.
