TL;DR: In this paper, the metal-induced gap states (MIGS) were suppressed and degenerate states in the metal dichalcogenides (TMDs) spontaneously formed in contact with bismuth.

TL;DR: This work fabricates a fully flexible and integrated rectenna that achieves wireless energy harvesting of electromagnetic radiation in the Wi-Fi band with zero external bias (battery-free) and provides a universal energy-harvesting building block that can be integrated with various flexible electronic systems.

TL;DR: It is found that the substrates can tune the electronic energy levels in MoS2 due to charge transfer at the interface and the reduction state of CeO2 as an oxide substrate affects the interface charge transfer withMoS2.

TL;DR: It is shown that the PL QY of CVD-grown monolayers can be improved from ∼0.1% in the as-grown case to ∼30% after treatment, with enhancement factors ranging from 100 to 1500× depending on the initial monolayer quality.

TL;DR: A theoretical model is reported to estimate the contact resistance between graphene and metal electrodes using density-functional theory and non-equilibrium Green's function methods and generates values which are in good agreement with the experimental results.
