Dear QE users and developers, I am doing hybrid-functional calculations, and I am confused about the setting of ecutvcut. In the examples of Si, for pbe0-type hybrid functional, the ecutvcut is set to be 0.7Ry, while for hse-type hybrid functional with a screened Coulomb potential, ecutvcut is just set as default which is 0.0Ry. Could anyone explain why? For a typical semiconductor with s or p valence orbitals, what kind of ecutvcut value is recommended?
Thanks a lot. best, Jianpeng Liu ------------------------------------- Ph.D. candidate, Department of physics and astronomy, Rutgers University -------------------------------------
