Strain and structure heterogeneity in MoS2 atomic layers grown by chemical vapour deposition

Large-size monolayer molybdenum disulfide (MoS2) has recently been produced via chemical vapour deposition (CVD), yet its structures and physical properties are yet to be fully explored. Here, the authors study the growth-induced strain in CVD-grown MoS2 and strain-based bandgap engineering of MoS2.
