Uniform nucleation and epitaxy of bilayer molybdenum disulfide on sapphire

Lei Liu et al.

Summary: This study reports the successful nucleation of bilayer molybdenum disulfide (MoS2) on c-plane sapphire, achieving uniformity in the nucleation process. The design of atomic terrace height on c-plane sapphire allows for an edge-nucleation mechanism and the coalescence of MoS2 domains into continuous, centimeter-scale films. Field-effect transistor devices based on bilayer MoS2 channels show improved mobility and reduced variation compared to monolayer films.

Ultraefficient Electrocatalytic Hydrogen Evolution from Strain-Engineered, Multilayer MoS2

Dohyun Rhuy et al.

Summary: This paper presents an approach to develop ultra-efficient catalysts for the hydrogen evolution reaction (HER) using low-cost, bulk multilayer MoS2. By transferring MoS2 flakes to gold thin films and inducing a local phase transition through surface wrinkles, the authors achieved HER activity comparable to platinum. The superior performance was attributed to the combined effect of the phase transition and improved charge transfer resistance through desulfurization.

Strained Epitaxy of Monolayer Transition Metal Dichalcogenides for Wrinkle Arrays

Jingwei Wang et al.

Summary: In this study, large-area monolayer TMDCs wrinkle arrays were fabricated directly on m-quartz substrate using strained epitaxy. By quenching the TMDCs after growth, the uniaxial thermal strain is released as wrinkle arrays along the quartz direction. The size of WS2 wrinkles can be finely modulated by changing the quenching temperature, inducing changes in optical properties and enhanced chemical reactivity.
