Monolayer molybdenum disulfide (MoS₂) has attracted tremendous attention due to its promising applications in high-performance field-effect transistors, phototransistors, spintronic devices, and nonlinear optics. The enhanced photoluminescence effect in monolayer MoS₂ was discovered and, as a strong tool, was employed for strain and defect analysis in MoS₂. Recently, large-size monolayer MoS₂ has been produced by chemical vapor deposition but has not yet been fully explored. Here we systematically characterize chemical vapor deposition grown MoS₂ by PL spectroscopy and mapping, and demonstrate non-uniform strain in single-crystalline monolayer MoS₂ and strain-induced band gap engineering. We also evaluate the effective strain transferred from polymer substrates to MoS₂ by three-dimensional finite element analysis. In addition, our work demonstrates that PL mapping can be used as a non-contact approach for quick identification of grain boundaries in MoS₂.
