<div dir="ltr">Hello All<div><br><div>I am going to do phonon calculations for Ba, Ga, Ge semiconductor alloys but their available pseudopotentials are not of the same type. </div><div>They have different exchange correlations functionals. </div>
<div>Do I have to generate all necessary pseudopotentials myself? </div><div>Are these differences between XC functionals negligible?</div><div>For example can I apply Ga.pw91-n-van.UPF and Ge.pw91-n-van.UPF along with Ba.pw91-nsp-van.UPF?</div>
<div>Are above mentioned pseudopotentials proper for phonon calculations?</div><div>I don't know exactly the meaning of pw91, pbe, n,van,nsp,meta,tm ,.... abbreviations. </div><div>Where can I find a comprehensive information about them?</div>
<div><br></div><div>Best regards,Payam Norouzzadeh </div></div></div>
