<br>
as for the NCPP there are numerous PP for different elements, for instance, I often use the ONCVPSP (Optimized Norm-Conservinng Vanderbilt PSeudopotential) by D. R. Hamann (Phys. Rev. B 88, 085117 (2013)) which can be found on

> I'm trying to calculate the dielectric functions of the materials. By searching on the internet, the dielectric functions can be calculated by using the epsilon.x code in the QE package. However, I found that there is a limitation that requires only norm-conserving
pseudopotential (NCPP). I look into the pseudopotential library on these 2 websites,<br>
