Heterostructures for charge‐carrier manipulation have laid the foundation of modern optoelectronic devices, such as photovoltaics and photodetectors. High‐performance heterostructure devices usually impose stringent requirements on the material quality to sustain efficient carrier transport and charge transfer, thus leading to sophisticated fabrication processes. Here, a simple yet efficient strategy...
Using the MoS2‐WTe2 heterostructure as a model system combined with electrochemical microreactors and density function theory calculations, it is shown that heterostructured contacts enhance the hydrogen evolution reaction (HER) activity of monolayer MoS2. Two possible mechanisms are suggested to explain this enhancement: efficient charge injection through large‐area heterojunctions between MoS2 and...
Creating heterojunctions between different 2D transition‐metal dichalcogenides (TMDs) would enable on‐demand tuning of electronic and optoelectronic properties in this new class of materials. However, the studies to date are mainly focused on hexagonal (2H) structure TMD‐based heterojunctions, and little attention is paid on the distorted octahedral (1T') structure TMD‐based heterojunctions. This...
