Özet

We performed first-principles calculations on band structures and optical properties of perovskite AgNbO3 compound in paraelectric phase under 0-50 GPa employing DFT within LDA with ABINIT package. The band gaps and optical properties under pressure were studied and discussed. Moreover, real and imaginary parts of complex dielectric function, energy-loss spectrum, refractive index, extinction and absorption coefficients under pressure were obtained and discussed.
