[CPMD-list] Is there any adapted BLYP-USPP for silicon?

[osirixu-cpmd at yahoo.com.cn]

Dear cpmders,

    Is there any adapted 'ultra-soft'
BLYP-PSEUDOPOTENTIAL for silicon? 
I just found a silicon USPP using PBE as DFT
(Si_VDB_PBE_NLCC.psp) in 
your homepage yet.
 
    Btw, is it a good idea to firstly use a USPP to
equilibrate the 
system, (e.g. doing geometry optimization and
CLASSICAL MD), and then 
re-optimize it using a corresponding norm-conserving
pseudopotential?
    
    Best Wishes!
