We apply this approach to bulk ZnO and bulk ZnS. Aswegen, H. Verleger, Naturwissenschaften 47, 131 (1960), Zheng Xing Huang, Zhen An Tang, Jun Yu, Suyuan Bai, Phys. According to the PBE + D2 scheme, a semi-empirical correction term is added to the total energy by evaluating atomic pair interactions, while, in the vdW-DF2 and rVV10 schemes the nonlocal contribution is calculated ab initio.

After test calculations on the bulk structure, a kinetic energy cutoff of 30 Ry is adopted to truncate the plane wave expansion in all the calculations apart Therefore, the presented approach is parameter free.
