Dear Steve and mpb community
I am looking to calculate DOS of a 3D PC. I have tried the file .scm but it=
shows a high density at zero and some low frequencies. I have tried a few =
samples ( photonic crystal structures, even I tried diamond.ctl) and all of=
them have the same problem. So I prefer working with two approaches (Gener=
alized-Gilat-Raubenheimer (GGR) method and tetrahedron (Tr) method).
The problem is how can I use these two methods to sweep the results (DOS) =
between two symmetry points ( like Gamma-L )not whole the Brilluion zone?
Thanks,
Regards
