    In this work, the WIEN2k computer code was used to investigate the structural, elastic, electronic, magnetic, optical, thermoelectric, and dynamic properties of the CoCrTe half-Heusler (HH) compound. The Full-Potential Linearized Augmented Plane Wave method and Density Functional Theory were both used in this work. To further understand the electronic band gap, we used the modified Becke Johnson exchange–correlation functional method. We investigated the CoCrTe HH compound's electronic characteristics using density of states plots and band structure plots. By calculating magnetic moments and observing the behavior of spin-polarized electronic states, we also investigated the magnetic properties. Additionally, the CoCrTe HH compound's elastic properties were identified. These characteristics, including stiffness, resilience, and overall stability, offer crucial information about how the material reacts to mechanical deformation. Properties studied emphasized that the compound is metallic, and it appears as a good thermoelectric material. Finally, the compound's dynamic properties show that it is dynamically stable as well as mechanically.

    The structural, elastic, electronic, magnetic, thermoelectric, and dynamic properties of the CoCrSe half-Heusler compound were examined using the WIEN2k code. Calculations were carried out in this work using the full-potential linearized augmented plane-wave (FP-LAPW) approach and density functional theory (DFT). We used modified Becke–Johnson (mBJ) exchange–correlation functional to improve the electronic energy bandgap. We studied different electronic properties of the CoCrSe compound, including density of states (DOS) and band structure plots. We also investigated the magnetic characteristics by computing magnetic moments and examining the behavior of spin-polarized electronic states. In addition, the elastic characteristics of the CoCrSe compound were determined. These properties, such as stiffness, resilience, and general stability, provide vital insights into the material’s response to mechanical deformation. The calculated elastic constants indicate that CoCrSe it is mechanically stable, brittle, and anisotropic. On the other hand, the compound is dynamically stable. Finally, we also check the thermoelectric properties. Graphical abstract: (Figure presented.)

    he present article has utilized the WIEN2k computational code to examine the structural, elastic, electronic, magnetic, thermoelectric, and dynamic aspects of the CoCrS Half-Heusler (HH) compound. In this work, calculations have been performed by utilizing the full-potential linearized augmented plane wave method using density functional theory. The electronic bandgap was better interpreted by using the modified Becke–Johnson exchange–correlation functional. We evaluated various electronic properties of the CoCrS HH compound, including band structure plots and density of states. Furthermore, we examined the magnetic characteristics through the computation of magnetic moments and the examination of the spin-polarized electronic state behavior. We also determined the elastic properties of the CoCrS HH compound. These properties, which include stiffness, resilience, and general stability, provide important information about how the material responds to mechanical deformation. Moreover, we explored the electronic structure and found that type 5 of CoCrS exhibits a metallic behavior. In addition, we examined the compound’s thermoelectric properties. Finally, the dynamical properties indicate that type 5 of CoCrS is dynamically stable.
