Charge transfer in P-doped graphene

Post by ihkwon »

Hello,
I got the ACF.dat file using bader analysis. I ran it with VASP.

The simulation model is Phosphorus doped graphene with 18 atoms in an unit cell.

ACF.dat file is the below.

#18 atom is phosphorus and the others are all carbon atoms.

In this case, is the way to calculate the charges of atoms right like this?

the charge of P = 5- 2.6815 = 2.3185e (positive charge)
the charge of C = 4- each CHARGE

the charge 2.3185e is reasonable?

I would appreciate for any advice.
