Abstract: SrAl₂O₄:Eu²⁺, Dy³⁺ thin films were prepared using the pulsed laser deposition (PLD) technique and the variation of morphological, photoluminescence and structural properties with the oxygen pressure were studied. The atomic force microscopy (AFM) and scanning electron microscopy (SEM) were employed in the films morphological measurements. The He-Cd... Show More

Abstract: We used the first-principles calculations based on density functional theory to calculate the electronic and optical properties of wurtzite CuInS2 (WZ-CuInS₂) in which the copper and indium atoms share the same lattice site. It is found that WZ-CuInS₂ is metallic for local aggregative indium and copper atomic configurations, or is a semiconductor f... Show More
