[Pw_forum] Virtual crystal approximation for vacancy

Dear all,

I am considering to use virtual crystal approximation to study a system 
with vacancy doped, and I do not know what I am supposed to generate a 
VCA psuedopotential for a mixture of an atom and a vacancy. I guess it 
is zero for the vacancy but I am not sure. Any ideas please? Thanks very 
much.

Best,

Yuning
