Here we use 1D A5B6C7 (A:Sb; B:S,Se;C:I) based layers in air background. We have theoretically calculated photonic band structure and optical properties of A5B6C7 (A:Sb; B:S,Se; C:I) based PCs. In our simulation, we employed the finite-difference time domain(FDTD) technique and the plane wave expansion method (PWE) which implies the solution of Maxwell equations with centered finite-difference expressions for the space and time derivatives.eninfo:eu-repo/semantics/openAccessFibonacci photonic crystal, SbSI photonic crystal, supercell photonic crystalArticle
