Semiconducting transition metal dichalcogenides (TMDC) are 2D materials, combining good charge carrier mobility, ultimate dimension down-scalability, and low-temperature integration. These properties make TMDCs interesting for flexible electronics, where the thermal fabrication budget is strongly substrate limited. In this perspective, an overview of state TMDC research provided by evaluating t...

Abstract The cleaning of two-dimensional (2D) materials is an essential step in the fabrication future devices, leveraging their unique physical, optical, and chemical properties. Part these emerging 2D are transition metal dichalcogenides (TMDs). So far there limited understanding “monolayer” TMD materials. In this study, we report on use downstream H 2 plasma to clean surface monolayer WS gro...

We calculate the torsional moduli of single-walled transition metal dichalcogenide (TMD) nanotubes using ab initio density functional theory (DFT). Specifically, considering forty-five select TMD nanotubes, we perform symmetry-adapted DFT calculations to for armchair and zigzag variants these materials in low-twist regime at practically relevant diameters. find that follow trend: MS$_2$ $>$ MSe...

Transition-metal dichalcogenide (TMDC) homo- and heterostacks hold tantalizing prospects for being integrated as active components in future van der Waals (vdW) electronics optoelectronics. How...

With the massive consumption of fossil fuels and its detrimental impact on the environment, methods of generating clean power are urgent. Hydrogen is an ideal carrier for renewable energy; however, hydrogen generation is inefficient because of the lack of robust catalysts that are substantially cheaper than platinum. Therefore, robust and durable earth-abundant and cost-effective catalysts are ...

The detection of specific DNA sequences plays a critical role in the areas of medical diagnostics, environmental monitoring, drug discovery and food safety. This has therefore become a strong driving force behind the ever-increasing demand for simple, cost-effective, highly sensitive and selective DNA biosensors. In this study, we report for the first time, a novel approach for the utilization ...

Twinned growth behaviour in the rapidly emerging area of two-dimensional nanomaterials still remains unexplored although it could be exploited to fabricate heterostructure and superlattice materials. Here we demonstrate how one can utilize the twinned growth relationship between two two-dimensional materials to construct vertically stacked heterostructures. As a demonstration, we achieve 100% o...
