Dear quatum espresso users.
i tried to compute the polarization of GaN i found that 's equal to =-2.36
in the same larticles i found that's = to 0.029 c/m2
such as the polarizaion had 2 tyes haw i can compuye the piezoelctric
polarisation.? and why the code give the value underestimaed compared to
the exprimental one?
thanks in advance
