Dear Prof. ;

Thanks for your great informations about build doping atoms,

and now we consider the real intrinsic defect structure for LiNbO3

single crystal, as people know about Nb vacancy (means there

is a hole on Nb atom site) can be exist in this crystal, and our

question is; The input file is correct or not?

ps: because we had not see the relation example, maybe you

can remark the mistake on it and e-mail back.

Thanks for your time and help!

Pei-chang Tsai
