Degree-Based Hybrid Topological Indices and Entropies of Wavy Zigzag Nanoribbons

Abstract

Graphene nanoribbons (GNRs) have recently accumulated attention as alternative 2D semiconductors due to their remarkable electronic properties. The topological and entropy properties of graphene nanoribbons are very important to fully understand their electronic properties. Graphene nanoribbons with zigzag-shaped edges are narrow strips of graphene characterized by edges that form a zigzag pattern. In this study, we have obtained the analytical expressions for degree-based topological indices to uncover the structural properties of graphene nanoribbons composed of nanographene units with zigzag-shaped edges. Furthermore, we demonstrate the usefulness of different variations of hybrid arithmetic, geometric, harmonic, and Zagreb degree-based topological and entropy indices for these wavy zigzag nanoribbons.
