[Pw_forum] SOC didn't make difference in GaAs band structure

Dear all,

I'm trying to calculate GaAs band structure with
spin orbit coupling (SOC), but am sorry that I'm
relatively a novice about density functional theory.
I still don't get the right band structure of GaAs.
Could you please help me correct my mistakes?

The problem is that SOC didn't make difference
in the band structure plot of GaAs. As you see
in the attached ps files, "gaas_bands.ps" with SOC is
quite the same to the band structure plot without SOC.

  I plotted those bands along L - Gamma - X path and
guess that the Fermi level is around 7.0 eV.
I did this band calculation using the attached input files
like the following.

$ pw.x < gaas.scf.david.in > gaas.scf.david.out
$ pw.x < gaas.bands.david.in > gaas.bands.david.out
$ bands.x < gaas.post.bands.in > gaas.post.bands.out
$ plotband.x < gaas.plotband.in > gaas.plotband.out

Probably I miss some important parameters to
deal with SOC, but I cannot figure it out from
the documents in the network.  So I'd be grateful
if you tell me about my possible mistakes or
give me any advice.

with my best regards,
Masa

     one-electron contribution =    -120.23899283 Ry
     hartree contribution      =      45.04782354 Ry
     xc contribution           =     -50.87688062 Ry
     ewald contribution        =     -93.02095149 Ry
     one-center paw contrib.   =    -234.87767803 Ry

     convergence has been achieved in   8 iterations
