Dear QE users<br><br>I am trying to do phonon calculations on AlN at non-zero fermi temperature to get forces recalculated for higher temperatures. But since I need to use smearing for that the code won't do LO-TO splitting as is needed in a semiconductor. Normally to get LO-TO splitting handled correctly all I need to do is omit the smearing keyword, but since I can't do it now, is there anything that I can do to get the splitting even while using smearing?<br>
Grateful for any suggestions.<br><br>Hans Lind<br>PhD student<br>Linköping University, Linköping, Sweden<br>
