Dear Iwan, take a look at epsilon.x inside PP directory. Be careful, epsilon.x only implements RPA (Random Phase Approximation) dielectric function with no local fields effects and without the nonlocal part of the pseudopotential.<div>

Currently I am running TM doped ZnO simulation using Quantum Espresso.<br> <br>At the moment, I plan to calculate dielectric function (frequency<br>dependent) of my model. I have read the manual and other sources<br>but I hardly find how to calculate them.<br>
<br>My question is, does QE have feature to calculate frequency dependent dielectric function ?<br>If yes, could anyone tell me the main steps to calculate them ?<br><br>Regards,<br><br>Iwan
