The current research paper presents a first-principles study of the effects of doping Zno with transition metals such as Yttrium (Y) and Vanadium (V) on its structural, electronic, thermal stability, and optical characteristics. Replacing these Zn atoms with the dopants results in a significant increase in the dielectric properties and conductivity of the material. Elastic constants are then calculated to determine the mechanical stability of the doped structures, confirming their structural integrity. The NVT ensemble is utilized to prove the thermal stability. Computational modelling is done in Material Studio where the simulations are done in CASTEP which can allow a detailed analysis of the doped ZnO systems. The tests done prior are band structure, X-ray diffraction (XRD) patterns, thermal stability, and optical properties like conductivity, reflectivity, and the refractive index. The results indicate that Y and V doping have the potential to alter the electronic structure of ZnO greatly, which has bright opportunities to enhance the functioning of ZnO in optoelectronic and dielectric devices. Besides broadening our knowledge about doped ZnO on the atomic scale, these findings can form a powerful basis of experimental validation and developing materials in the future.
