Abstract

The theoretical approach was employed to comprehensively investigate the structural, dynamical, band structure, optical characteristics, and elastic anisotropy of CuAlS₂. The determined lattice parameters (a and c), elastic properties exhibit with the available data. The band structure and density of state indicates that CuAlS₂ exhibits semiconductor properties, characterized by a direct band gap measuring approximately 1.791 eV. The mechanical stability and optical properties of CuAlS₂ was calculated and analyzed.
