Abstract:

For the couple of chalcopyrite compounds, we have theoretically studied the various properties for example structural, electronic optical and mechanical properties. The band structure curve, the density of states as well as the total energy have been investigated with the help of ATK-DFT by using the pseudo-potential plane wave method. For the LiInS2 and LiInSe2 chalcopyrites, we have found that these compounds possess direct band gap; which is 3.85 eV and 2.61 eV for LiInS2 and LiInSe2 respectively. It shows that the band gap is decreasing from ‘S’ to ‘Se’ as well as the B/G ratio called Pugh

Abstract A series of Ca-based novel chalcopyrite compounds have been studied by means of the full-potential linearized augmented plane wave method. In this work, we have used one of the utmost precise exchange and correlation functional of Tran-Blaha modified Becke Johnson (TB-mBJ) for the investigation of electronic as well as optical properties of Ca based chalcopyrite compounds namely, CaXY2 (X = Ge, Sn; Y = N, P, As). The computed energy bands and density of states reveals the semiconducting nature of all these studied compounds. The bandgap of CaXY2 (X = Ge, Sn; Y = N, P, As) compounds ar

Abstract:

Electric field gradients have been measured at substitutional lattice sites in ternary semiconductors using Perturbed γ -γ Angular Correlation spectroscopy (PAC). The experimental results for AIBIIIC2 chalcopyrite structure compounds and • AIIB2IIIC4IV defect chalcopyrites are compared with ab nitio calculations. The latter were carried out with the WIEN code that uses the Full Potential Linearized Augmented Plane Wave method within a density functional theory. The agreement between experiment and theory is in most cases very good. Furthermore, the anion displacements in AgGaX2 -compounds (X:

Abstract:

Chalcopyrites are ternary semiconductor compounds with successful applications in photovoltaics. Certain chalcopyrites are well researched, yet others remain understudied despite showing promise. In this study, we use ab initio methods to study CuGaS2, AgGaS2, and CuGaSe2 chalcopyrites with a focus on their less studied solid solutions. We use density functional theory (DFT) to study the effects that atomic configurations have on the properties of a solid solution and we calculate the optical absorption spectra using a many-body perturbation theory. Our theoretical simulations predict that exc

Abstract:

The purpose of this study is to propose the flotation procedure of seafloor massive sulfide (SMS) ores to separate chalcopyrite and galena as froth and sphalerite, pyrite, and other gangue minerals as tailings, which is currently facing difficulties due to the presence of water-soluble compounds. The obtained SMS ore sample contains CuFeS2, ZnS, FeS2, SiO2, and BaSO4 in addition to PbS and PbSO4 as Pb minerals. Soluble compounds releasing Pb, Zn2+, Pb2+, and Fe2+/3+ are also contained. When anglesite co-exists, lead activation of sphalerite occurred, and thus sphalerite was recovered together
