Topological indices and entropy measures in cove-edged graphene nanoribbons using curve-fitting models

Abstract

Graphene nanoribbons (GNRs) with precise structural properties have become attractive options for next-generation nanoelectronics because of their adaptable electrical topologies and their uses in quantum electronics, photovoltaics, and transistors. These interesting properties have recently collected significant attention in the field. Cove-edged graphene nanoribbons (CGNRs) are especially interesting because of their distinctive electromagnetic properties. This type of nanoribbon features asymmetric edges composed of sequential hexagons, exhibiting remarkable mechanical and electrical properties. In this paper, we find the new Zagreb-type topological indices and the corresponding entropy measures of graphene nanoribbons with curved edges. We establish correlation analysis between the Zagreb-type indices and entropy measures through the curve-fitting model and the Pearson correlation coefficient. The results of this study may reduce the amount of work needed to investigate the physicochemical characteristics of graphene nanoribbons with curved edges.
