Origins of Moire Patterns in CVD-grown MoS₂ Bilayer Structures at the Atomic Scales.

ABSTRACT: The chemical vapor deposition (CVD)-grown two-dimensional molybdenum disulfide (MoS₂) structures comprise of flakes of few layers with different dimensions. The top layers are relatively smaller in size than the bottom layers, resulting in the formation of edges/steps across adjacent layers. The strain response of such few-layer terraced structures is therefore likely to be different from exfoliated few-layered structures with similar dimensions without any terraces. In this study, the strain response of CVD-grown few-layered MoS₂ terraced structures is investigated at the atomic scales using classic molecular dynamics (MD) simulations. MD simulations suggest that the strain relaxation of CVD-grown triangular terraced structures is observed in the vertical displacemen
