<div>Dear all</div>
<div> </div>
<div>I want to calculate the phonon lifetime by QE. I have read some
replays about this question in this forum , and the thesis "Anharmonic
Phonon Lifetime in Semiconductors from Density-Functional Perturbation
Theory" . However I have not understand how to use the outcome of d3.x .
Actually no ideas about what the d3.x calculate . And I can't find
an answer about this question in the forum .</div>
<div> </div>
<div>Please forgive my ignorance . And I hope someone could tell me
it is not a joke that QE can give us the outcome about phonon lifetime .</div>
<div> </div>
<div>Thanks in advance . And best wishes .</div>
