Dear QE Members,
I am currently using Quantum ESPRESSO version 7.1 to perform a geometry
optimization of a LiCoO2 (104) slab model. However, I have encountered an issue
where the estimated SCF accuracy remains very high, showing no signs of
convergence. I am seeking your guidance on how to address this problem.
Below are the specifics of my setup:
Pseudopotentials: SSSP Efficiency PBEsol (version 1.3)
Hubbard + U: U value of 3.3 for Co 3d orbitals
Spin polarization: Enabled with initial magnetic moments set to 0.2 for Co, and
0 for O and Li
The accuracy come up:
