[QE-users] Soft Hydrogen Pseudopotentials

[Matthieu Fortin-Deschênes]

Hi all,

I want to use hydrogen to passivate the bottom surface of a surface  
slab. However, I notice that H PPs usually require a high ecutwfc,  
which restricts the size of the system I can consider.

Are there any PPs with lower required ecutwfc available for that purpose?
And would this negatively effect the accuracy of the calculations on  
the other side of the surface slab?

Thank you,
