Abstract null null Although atomically thin two-dimensional graphene is of interest for next-generation electronic device applications owing to its outstanding properties, a crucial issue concerning the stable operation of graphene-based devices under ambient conditions still remains for industrial applications. Because the electrical performance of graphene-based devices is largely affected by polar atmospheric species such as water molecules (H2O), it is important to eliminate this detrimental effect. In the present study, we report a facile method to enhance the moisture stability of graphene field-effect transistors (FETs) by modulating the surface energy of substrates. We found that this simple method enables us not only to retain the way to secure field-effect mobility, but also to improve the stability of graphene FETs. The device on the surface-modulated substrates showed excellent moisture stability, even under harsh humid environments. We expect that the proposed method will be widely useful for the improvement of ambient stability in various 2D material-based electronics.

Graphene oxide (GO), which has many oxygen functional groups, is a promising candidate for use in moisture-responsive sensors and actuators due to the strong water-GO interaction and the ultrafast transport of water molecules within the stacked GO sheets. In the last 5 years, moisture-responsive actuators based on GO have shown distinct advantages over other stimuli-responsive materials and devices. Particularly, inspired by nature organisms, various moisture-enabled soft robots have been succes...

Lead-free double perovskites have great potential as stable and nontoxic optoelectronic materials. Recently, Cs2 AgBiBr6 has emerged as a promising material, with suboptimal photon-to-charge carrier conversion efficiency, yet well suited for high-energy photon-detection applications. Here, the optoelectronic and structural properties of pure Cs2 AgBiBr6 and alkali-metal-substituted (Cs1-x Yx )2 AgBiBr6 (Y: Rb+ , K+ , Na+ ; x = 0.02) single crystals are investigated. Strikingly, alkali-substituti...

Abstract In this work we expose transferred multi-layer graphene (i.e. graphene separated from the substrate used for graphene growth and placed onto a carrier sample) to Extreme Ultraviolet light and water, in the presence of hydrogen. It is observed that graphene oxidizes by breaking down its aromatic structure into the enol form of 1,3-diketone. Furthermore, this oxidation is compared with studies on as-grown multi-layer graphene samples, which are shown to not oxidize. Our work shows that ox...

The reduction and patterning of graphene oxides (GOs) have broad applications in gene transfection, cell differentiation control, etc. However, two-dimensional (2D) photoreduction technologies (such as UV lithography) fail to realize the three-dimensional (3D) reduction and patterning of GO, limiting its applications in 3D electronic device interconnection and 3D graphene organ-on-a-chip. Here we developed 3D reduction and patterning of GO by femtosecond laser direct writing (FsLDW) technology. ...

: An insight into the analogies, state-of-the-art technologies, concepts, and prospects under the umbrella of perovskite materials (both inorganic-organic hybrid halide perovskites and ferroelectric perovskites) for future multifunctional energy conversion and storage devices is provided. Often, these are considered entirely different branches of research; however, considering them simultaneously and holistically can provide several new opportunities. Recent advancements have highlighted the pot...

: The strong interaction between graphene oxides (GO) and water molecules has trigged enormous research interest in developing GO-based separation films, sensors, and actuators. However, sophisticated control over the ultrafast water transmission among the GO sheets and the consequent deformation of the entire GO film is still challenging. Inspired from the natural "quantum-tunneling-fluidics-effect," here quantum-confined-superfluidics-enabled moisture actuation of GO paper by introducing perio...

This article describes a novel method of growing graphene directly on a flexible substrate at low temperatures using plasma-enhanced chemical vapor deposition with a solid aromatic hydrocarbon source, 1,2,3,4-tetraphenylnaphthalene (TPN), which acts as the feedstock for graphene growth. TPN is embedded with copper ions that are reduced under the growth conditions to copper nanoparticles that catalyze the graphene growth and then evaporate to leave pristine graphene. Strong covalent bonds between...

Abstract In this work, we reported the fabrication of flexible NO2 sensors arrays operating at room temperature on a composite film of In2O3 and graphene oxide (GO) by direct laser writing (DLW) technology. The laser treatment not only induced the photoreduction of GO, leading to a highly porous structure due to the removal of oxygen groups, but also permitted mask-free patterning through a programmable manner, enabling flexible integration of sensor arrays on any substrates. We demonstrated the...
