[QE-users] Direction of ferroelectric polarization

[Rajneesh Chaurasiya]

Dear expert,

I have an question regarding the direction of ferroelectric polarization.
Position of hexagonal unit cell are A (2/3 1/3 x), B (2/3 1/3 y) and C (1/3
2/3 z). Here i have considered monolayer and considered the gdir 1, 2 and
3, in which observed the ferroelectric polarization along (100), (-0.5
0.866 0) and (001) direction. The value of total ferroelectric polarization
should be zero as per report but i couldn't observed. please suggest me how
to define the direction for ferroelectric polarization.


Thank you.
