Electronic energy structure and optical properties of In$_{4}$CdI$_{6}$ from $\textit{ab initio}$ calculations

This work presents the $\textit{ab initio}$ calculations of the electronic energy spectrum of the In$_{4}$CdI$_{6}$ compound. The study was conducted within the framework of density functional theory (DFT), using local density approximation (LDA) and general gradient approximation (GGA) pseudopotent
