This is the example of silicon calculation. The Wien2k calculation was made to | ||
obtain forces with 2x2x2 k-point mesh for the supercell, PBE, and the lattice | ||
parameters in Si.struct. | ||
|
||
`phono3py_disp.yaml` is generated by | ||
|
||
``` | ||
% phono3py --wien2k -d --dim 2 2 2 -c Si.struct | ||
``` | ||
|
||
To create `fc3.hdf5` and `fc2.hdf5`, | ||
|
||
``` | ||
% phono3py-load | ||
``` | ||
|
||
Using 11x11x11 sampling mesh, lattice thermal conductivity is calculated by | ||
|
||
``` | ||
% phono3py-load --mesh 11 11 11 --br --ts 300 | ||
``` | ||
|
||
`kappa-m111111.hdf5` is written as the result. The lattice thermal conductivity | ||
is calculated as 119.1 W/m-K at 300 K. This becomes, with 19x19x19 sampling | ||
mesh, 128.1 W/m-K. | ||
|
||
The .scf files for supercells are found in `Si1_structS_scf.tar.xz`. If phono3py | ||
is properly installed, the following command should work. | ||
|
||
``` | ||
% phono3py --cf3 Si1_structS_scf/Si1.structS-{00001..00111}.scf | ||
``` |
