[Pw_forum] surface phonon calculations

[L.T. Kong]

Dear all,

I am going to do something with the surface phonons of metals, especially
for a surface with an absorbate. But I have no idea how can I fulfil this.
I have read and tried the example02, but I am not sure if I should do the
same way as it?
For a surface simulated by a slab supercell, there would be two surfaces,
actually, how can I mimic the bulk like substrate? By including thicker slab
or just fixed one side as is done in a surface relaxation?

If anyone can share the script to do so, it will be highly appreciate.

Thank you.
