Query: Tailoring the structural and electronic properties of graphene-like ZnS
  monolayer using biaxial strain   Our First-principles Full-Potential Density Functional Theory (DFT)
calculations show that a monolayer of ZnS (ML-ZnS), which is predicted to adopt
a graphene-like planar honeycomb structure with a direct band gap, undergoes
strain-induced modifications in its structure and band gap when subjected to
in-plane homogeneous biaxial strain ($\delta$). ML-ZnS gets buckled for
compressive strain greater than 0.92%; the buckling parameter $\Delta$ (= 0.00
\AA\, for planar ML-ZnS) linearly increases with increasing compressive strain
($\Delta = 0.435$ \AA \,at $\delta = - 5.25$%). A tensile strain of 2.91% turns
the direct band gap of ML-ZnS into indirect. Within our considered strain
values of $|\delta| < 6%$, the band gap shows linearly decreasing (non-linearly
increasing as well as decreasing) variation with tensile (compressive) strain.
These predictions may be exploited in future for potential applications in
strain sensors and other nano-devices such as the nano-electromechanical
systems (NEMS).
