Niobium pseudopotentials

[jadhikari]

Hello,
Just wondering about more of already generated Niobium pseudopotentials (GGA, zion13) for testing purposes.
Not the input.
If possible please let us know the references.

Thanking you,

Hi, I've just uploaded my Nb atompaw datasets to the contributed PAW area, both LDA and GGA. They seem to give pretty good results. Is this what you are looking for?

Prof. Joe Zwanziger,

Thank you very much for the Nb-dataset. This is my next step for chemical shielding calculations.

Actually, I am looking for Nb-pseudopotentials for the relaxation of perovskites. It is to compare the results from various sources and to understand the proper use of psps of various atoms in different approximations. I have just started generating new ones using FHI98PP and OPIUM.

Once again thanking you.

Sincerely,
Subin A

Hi,
Regarding earlier mail, it is electric field gradient calculations and not chemical shielding calculations.

Thanking you,

Hi, just a reminder that the EFG calculation can only be done with PAW, not with NCPP's (therefore not with opium or fhi). If your ultimate object is NMR, you probably should stick with PAW. You can do all the relaxation calculations with PAW just like NCPP, and usually faster anyway.

Let me know if I can be of help,

Joe

p.s. are you working with Luis? If so pass greetings from me!
