<br>
Thank you very much, <br>
<br>
so far, I follow your recommendation and I will feedback with my finding,<br>
<br>
Best wishes,<br>

<div>Dear all,<br>
The mentioned equations are just for for ZnO, and they use some experimental values of the conductivity. However, the method can be replicated for other II-VI or III-V compounds. I would not dare to replicate it for a different class of material.
<br>
<br>
</div>
Computing directly the carrier lifetime is mainly a matter of eletron-phonon interactions and electron-defect interaction, and electron-hole recombination. All of them could be done with the help of Quantum ESPRESSO, using auxiliary codes, but I do not know
any implementation to do it. <br>
</div>
I hope someone hast and cat share it. <br>

Dear Abdullah
<div><br>
</div>
<div>Yes you can calculate indirectly all this parameter's by using Boltztrap code.</div>
<div><br>
</div>
<div>Boltztrap give you as output file ( carrier concentration, conductivity/carrier lifetime)</div>
<div><br>
</div>
<div>so by using this equation [1] you can calculate carrier lifetime </div>
<div><br>
</div>
<div>[1]:K.P.Ong, D.J.Singh, P.Wu, Phys. Rev. B 83 (2011) 115110.</div>
<div><br>
</div>
<div> carrier lifetime=2.53*(10^-5)*(T^-1)*(<wbr>n^(-1/3)) [1]</div>
<div><br>
</div>
<div>were T:temperatur, n: carrier concentration.</div>
<div><br>
</div>
<div>and if u want calculate mobility use this equation :</div>
<div><br>
</div>
<div> mobility=conductivity/(charge elementaire*carrier concentration)</div>
<div><br>
</div>
<div>i think if you have this parameters you can calculate diffusion length.</div>
