Dear Sir:
I am running a program conatining Tantalum and C,H atoms. I created VANDERBILT pseudopotential ( use uspp735) for Ta and use the GOEDECKER Norm-conserving pseudopotentials for C and H. Now I have three equiries as following:
1. I found the VANDERBILT pseudopotential are not applicable to K-points settings (Monkhorst-pack etc). It can only run after I delete the K-points Keywrods, ( that is with Gamma points?). I wonder whether there is a way to set k-points both applicable for VANDERBILT and other kinds of pseudopotentials?
2. I have also tried to generate Norm-conserving pseudopotentials via fhi98PP, but it cannot be read by CPMD. I have tired the script on http://www.cpmd.org/pipermail/cpmd-list/2002-February/000023.html, but it fails ( I tried to run it as a excutable file as well as add the scripts to the psgen file, but both failed). Is there other any source for generating Norm-conserving pseudopotentials that can be read via CPMD?
3. In the output file of CPMD, all the length, mass & energy are in A.U. unit. I think A.U. represents bohr for length &mass of one proton for the mass. But for the energy, is it in eV? The question seems too simple as I am a novice in this area.
Thanks & Best Regards!
Scott
