Re: HGH pseudopotential with GGA method??
Hello,
You have only a few elements for which HGH pseudopotentials are available for GGA on the abinit website (hydrogen, carbon and oxygen) and to be consistent, you should always use pseudopotentials made with the same exchange correlation i.e. do not use an HGH pseudo LDA with ixc 11 for example and reverse.

No no, it's much better than this - the whole GGA periodic table was generated by Matthias Krack:
http://cvs.berlios.de/cgi-bin/viewvc.cg ... er/abinit/
these pseudopotentials use the gth/hgh form, and most have an abinit-compatible version.

Hi...
thats what i wanted to know (HGH with ixc 11) because when i do that it works well and gives good results ...
I have another question please.. why pspnc ( Troullier-Martins ) pseudo. doest not gives good results?.. for example when i want calculate band gap energy for ZnS using pspnc pseudo.
thank u

I already used these pseudo. but it doesn't work I don't know why?!!
Thank you very much

I mean the link what you gave me contains pseudopotential file with pspcode equal to 10 but in abinit should be between 1 to 8
