Respected Sir/Friends, I have downloaded following pseudopotential files for Ti and O from quantum espresso website. In the web site it is written both are created using scalar relativistic method as written below. O.blyp-van_ak.UPF <http://www.quantum-espresso.org/wp-content/uploads/upf_files/O.blyp-van_ak.UPF> Pseudopotential type: ULTRASOFT Method: Vanderbilt ultrasoft Functional type: Becke-Lee-Yang-Parr (BLYP) exch-corr scalar relativistic
Ti.blyp-sp-van_ak.UPF <http://www.quantum-espresso.org/wp-content/uploads/upf_files/Ti.blyp-sp-van_ak.UPF> Pseudopotential type: ULTRASOFT Method: Vanderbilt ultrasoft Functional type: Becke-Lee-Yang-Parr (BLYP) exch-corr Semi-core state in valence scalar relativistic But inside for Oxygen pseudopotential file it is written as " 0 The Pseudo was generated with a Non-Relativistic Calculation". I am little bit confused about this. May I use these two files for TiO2 band structure calculation? And one more thing is while I try to run the calculation I got the following error for the above pseudopotential files " task # 0 from read_pseudo_nl : error # 6 Reading pseudo file (qfunc)" I did see these things for the following Ti and O pseudopotential files. X.pz-mt_fhi.UPF, X.pbe-mt_fhi.UPF Thanks With Regards, A.Suresh, Research Scholar, Madurai Kamaraj University, Madurai.
