Dear Amir, in the pslibrary project you can certainly find an US pseudo for Silicon. however Silicon is one of the least problematic elements and you probably don't need an US pseudo for it. The code can with no problem handle different pseudo types in the same run. best, stefano On 05/0

[Pw_forum] Comparing xspectra to experimental data: absolute energy shift

2016-08-04 Thread Hud Wahab
Hello QE community I am trying to compare the xspectra (5.3.0) and experimental absorption data at the carbon K-edge, that is, the measured energies for carbon K-edge between 285 eV and 320 eV. How does one shift the xspectra simulation to the absolute energy scale of the experiment? I think

Dear QE users I would like to use QE for calculating band gap with hybrid pseusopotentials approach. after going from the discussions available at different sites, I have done the calculation in this way: vc-relax the system, did scf and then nscf followed by band structure calculation. My que

Greetings Pwscf users & developers, I am doing relax calculation for 3x3x3 its giving some output without any error.But while doing relaxation for 4x4x4 its stopping without giving any error in iteration one. What might be the possible reason?? Am I missing something? Should I change any default pa
