I just calculate an interface between two compounds. No problem and<br>
results are as expected.<br>
however I would like to calculate the phonons at the interface (even<br>
more electron -phonon coupling but let's start with just phonons).<br>
Since my unit cell is huge, my question is :<br>
is there any way to calculate the phonons "only at the interface" by<br>
allowing to move the interface atoms ?? something like "selective<br>
dynamics"<br>
Thanks in advance<br>
<br>
