Dear Pwscf users,<br>I am doing electronic calculation of SnO2 in rutile structure. I am using Sn.pw91-n-van.UPF and O.pw91-van_ak.UPF <br>PP. With this i am getting a band gap of 7.2 eV, while LDA calculations (by other authors) shows band gap of 3.36 eV and experimental is 1.1 eV.<br>
<br>So is the PP which I am using gives this much band gap?<br>or there is some error in my cal.? I am sending the scf file. Please check it and suggest me.<br>thanks<br><br><br><br clear="all"><br>-- <br>Bipul Rakshit<br>
