Normalized unit cell volume of hexagonal ZGO as a function of pressure. Fitting the V–P data using Eq. (1) with the third-order Birch–Murnaghan equation of state, and the bulk modulus is shown in the figure. The red and green curve fit the data below 3.1 GPa and above 4.2 GPa by quadratic function respectively.
