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.eninfo:eu-repo/semantics/closedAccessElectronic StructureOptical PropertiesDensity Functional CalculationsArticle916N/AQ2653657WOS:000405421500007
