Various stacking patterns have been predicted in few-layer MoS₂, strongly influencing its electronic properties. Bilayer MoS₂ nanosheets have been synthesized by vapor phase growth. It is found that both A-B and A-A鈥?stacking configurations are present in bilayer MoS₂ nanosheets through optical images, and the different stacking patterns exhibit distinctive line shapes in the Raman spectra. By theory calculation, it is also concluded that the A-B and A-A鈥?stacking are the most stable and lowest-energy stacking in the five predicted stacking patterns of bilayer MoS₂ nanosheets, which proves the experimental observations.
