Hi I am trying to plot phonon band dispersion displacement vectors associated to each atom in my system. I have done ph.x part of calculation and I have pattern.xx.xml files for each q-point. I am trying to understand the file format so that I can visualize the directions of displacement vector

[QE-users] big difference between scf fermi energy and nscf fermi energy

2024-07-24 Thread Bhargab Kakati
Dear QE users, I am trying to find out the bandstructure of a semiconductor and noticed that there is a big difference between the Ferrmi energy computed from scf and nscf. If I consider the fermi energy from scf then the semiconductor becomes p-type and if I consider nscf fermi energy it will
