[Pw_forum] phonon dispersion

[Eyvaz Isaev]

Hi, 

I suppose, the best way to plot phonons is PlotPhon utility in  QE.
What you need is IFC-matrix (*.fc file).
See examples in /PlotPhon/Examples how to launch them.

Bests,
Eyvaz.

Dear all 
 
I want to calculate the phonon dispersion of B12 at the first Brillouin  Zone . 
i don't know which program should I use ? Please give me some advice . And if 
it's possible ,please give me a example ?

thanks in advance .
