A DFT Study of Vanadium Doped Gold Nanoalloy Clusters

Abstract

The electronic and optical properties of AunV (n=1-8) nanoalloy clusters have been investigated invoking Density Functional Theory (DFT) based descriptors. Conceptual DFT based global descriptors have been used to exhibit experimental properties qualitatively. In this report, the experimental properties of AunV (n=1-8) nanoalloy clusters are correlated in terms of DFT based descriptors viz., HOMO-LUMO energy gap, Hardness, Softness, Electronegativity, Electrophilicity Index and Dipole Moment. The doping of single vanadium atom in gold clusters enhances the stability of gold clusters and also display pronounced odd-even oscillation behaviors. The computed bond length of instant clusters are numerically close with experimental data. The linear regression analysis has been done in terms of correlation between our computed descriptors and their experimental counterparts.
