[Pw_forum] where does pp.x get degauss from for plot_num = 3?

[J. D. Burton]

Greetings,

 

I'm trying to use plot_num = 3 to image the metal induced gap states in a
metal/insulator heterostructure and what I'm getting doesn't make much
sense: there should be a roughly exponential decay into the insulator from
both interfaces, but I find the Fermi-level ldos in the insulator is roughly
the same as in the metal, and there are some regions in the metal where
there is essentially zero Fermi-level ldos.

 

Anyway, my question is: Where does the pp.x program get the value of degauss
that it uses to smear out the eigenvalues for the ldos calculation? I want
to try changing this to see what happens to the result.

 

Cheers,

J. D. Burton
