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
