Atomically thin tungsten disulfide (WS2), a structural analogue to MoS2, has attracted great interest due its indirect-to-direct band-gap tunability, giant spin splitting, and valley-related physics. However, the batch production of layered WS2 is underdeveloped (as compared with that MoS2) for exploring these fundamental issues developing applications. Here, using low-pressure chemical vapor deposition method, we demonstrate high-crystalline mono- few-layer flakes even complete layers can...
Controllable synthesis of monolayer MoS2 is essential for fulfilling the application potentials in optoelectronics and valleytronics, etc. Herein, we report scalable growth high quality, domain size tunable (edge length from ∼200 nm to 50 μm), strictly flakes or even complete films on commercially available Au foils, via low pressure chemical vapor deposition method. The as-grown samples can be transferred onto arbitrary substrates like SiO2/Si quartz with a perfect preservation crystal thus...

More significantly, these find a broad range real applications by enabling low-cost...
Electroepitaxy is recognized as an effective approach to prepare metal electrodes with nearly complete reversibility. Nevertheless, large-scale manipulation still not attainable owing complicated interfacial chemistry. Here, the feasibility of extending Zn electroepitaxy toward bulk phase over a mass-produced mono-oriented Cu(111) foil demonstrated. Interfacial Cu-Zn alloy and turbulent electroosmosis are circumvented by adopting potentiostatic electrodeposition protocol. The as-prepared...
Wearable humidity sensors are attracting strong attention as they allow for real-time and continuous monitoring of important physiological information by enabling activity tracking well air quality assessment. Amongst 2Dimensional (2D) materials, graphene oxide (GO) is very attractive sensing due to its tuneable surface chemistry, high area, processability in water, easy integration onto flexible substrates. However, hysteresis, low sensitivity, cross-sensitivity issues limit the use GO...
