The recently discovered two-dimensional (2D) layered semiconductor $\mathrm{Mo}{\mathrm{Si}}_{2}{\mathrm{N}}_{4}$ has aroused great interest due to its unique 2D material characteristics. In this study, we found that differences in the structural details for $\mathrm{Mo}{\mathrm{Si}}_{2}{\mathrm{N}}_{4}$ may lead to differences in the intensity of second harmonic generation (SHG) and its response to strain. Accordingly, …
