The real and imaginary parts of refractive index, dielectric function, optical absorption coefficient and reflectance have been calculated by using PBESOL functional. The obtained results show that the gap energy of ZnSe icreases nonlinearly with pressure. All of the optical properties at different pressures up to 14 GPa have been calculated and compared with each other. LA eng UL http://opsi.ir/article-1-593-en.html M3 ER -
