[Wien] Is there any relationship between DOS(E_F) and conductivity?

[Fecher, Gerhard]

Fast answer:
compare Fe and Cu and you have it.

The conductivity depends not only on the DOS at Ef but also on the setails of the bandstructure.
There is no way to compare whether Sodium, Copper, or Gold are more metallic or not.

Dear All,
We are working on two different metallic compounds. I have calculated
total DOS at Fermi level, DOS(E_F), for these two compounds. Our
result shows that the DOS(E_F) of the first compound is larger than
the  DOS(E_F) of the second compound. Can I conclude from this
observation that the first compound is more metallic than the second
compound? Can we compare conductivity of these two compounds using
their total DOS values at Fermi levels? Can you cite a reference in
this respect?
Best regards,
