Wafer-scale synthesis of monolayer WS 2 for high-performance flexible photodetectors by enhanced chemical vapor deposition

InterNano Industry News - May 26, 2018 - 3:45am
Abstract Two-dimensional (2D) nanomaterials have recently attracted considerable attention due to their promising applications in next-generation electronics and optoelectronics. In particular, the large-scale synthesis of high-quality 2D materials is an essential requirement for their practical applications. Herein, we demonstrate the wafer-scale synthesis of highly crystalline and homogeneous monolayer WS2 by an enhanced chemical vapor deposition (CVD) approach, in which precise control of the precursor vapor pressure can be effectively achieved in a multi-temperature zone horizontal furnace. In contrast to conventional synthesis methods, the obtained monolayer WS2 has excellent uniformity both in terms of crystallinity and morphology across the entire substrate wafer grown (e.g., 2 inches in diameter), as corroborated by the detailed characterization. When incorporated in typical rigid photodetectors, the monolayer WS2 leads to a respectable photodetection performance, with a responsivity of 0.52 mA/W, a detectivity of 4.9 × 109 Jones, and a fast response speed (< 560 μs). Moreover, once fabricated as flexible photodetectors on polyimide, the monolayer WS2 leads to a responsivity of up to 5 mA/W. Importantly, the photocurrent maintains 89% of its initial value even after 3,000 bending cycles. These results highlight the versatility of the present technique, which allows its applications in larger substrates, as well as the excellent mechanical flexibility and robustness of the CVD-grown, homogenous WS2 monolayers, which can promote the development of advanced flexible optoelectronic devices.

How to eliminate a graphene oxide 'oil spill' accident

InterNano Industry News - May 26, 2018 - 3:45am
Carbon nanomaterials, including graphene-based materials, are widely gaining popularity in practical applications of nanomanufacturing. As a result, it becomes more and more likely that the unwanted introduction of such materials into the environment may occur. In particular, aqueous habitats might be severely affected by any accidental carbon nanomaterials exposure. Researching these potential environmental toxicity effects, scientists have found that kaolin, a cheap and abundant clay, can act as a powerful antidote to remediate the toxic effects of graphene oxide.

Nano: a cleaner option?

InterNano Industry News - May 26, 2018 - 3:45am
Could nanotechnology tidy up the planet without leaving a dangerous residue of its own?It's likely that you've recently swirled nanotechnology down your sink. Antimicrobial silver nanoparticles, for example, are added to food containers, socks, and cleaning products such as floor polish. But could nanoparticles – measuring less than 100 nanometres wide – clean more than just your house? Could nanotechnology tidy up the planet without leaving a dangerous residue of its own?The European Environment Agency estimates that "potentially polluting activities" have occurred at nearly three million EU sites. But nanoparticles could remediate water, soil and air polluted by compounds such as heavy metals and aromatic hydrocarbons. With high reactivity and a larger surface area than the same mass of material in a larger form, nanoparticles are prime candidates for capturing and destroying pollutants. Continue reading...
