Re: [QE-users] Metal-substituted semiconductor: treat as metal or insulator for phonons

Hello ChrisIf the system is metallic, no matter how bad a conductor it can be, in a finite time it will be able to screen any constant electric field. This  is as to say that the static dielectric constant is infinite. Regards PietroIl 04 mar 2018 8:03 AM, Christoph Wolf

[QE-users] Metal-substituted semiconductor: treat as metal or insulator for phonons

Dear all, I have a fairly general question and I hope I can pick someone's brain: If an insulator or semiconductor is doped with a metal narrow bands determined by the crystal field emerge and often the fermi level lies within one of the bands, i.e. the "bands cut the fermi level", which is

Dear Paolo Giannozzi I think that the LDA+1/2 method is not implemented for PAW, because when i made another lda-1/2 test for USPP pseudopotential for Sb atom, it worked normally without any segmentation fault. However, iam interested in the PAW pseudopotential Is there any
