This is an example of Abinit interface.
|
|
|
|
To create supercells with displacements:
|
|
|
|
% phonopy --abinit -c Si.in -d --dim="2 2 2"
|
|
|
|
A perfect 2x2x2 supercell (supercell.in) and one 2x2x2 supercells
|
|
(supercell-xxx.in) of the conventional unit cell written in Si.in are
|
|
created. In addition, disp.yaml file is created. After force
|
|
calculation with the crystal structure in supercell-001.in, it is
|
|
needed to create FORCE_SETS file by
|
|
|
|
% phonopy --abinit -f supercell-001.out
|
|
|
|
Here .out files are supposed to contain the forces on atoms calculated
|
|
by Abinit and filenames can be chosen freely. The disp.yaml file has
|
|
to be put in the current directory. Now you can run phonon
|
|
calculation, e.g.,
|
|
|
|
% phonopy --abinit -c Si.in -p --dim="2 2 2" --pa="0 1/2 1/2 1/2 0 1/2 1/2 1/2 0" --band="1/2 1/2 1/2 0 0 0 1/2 0 1/2"
