Abstract

Anoutstanding way of findingneighborhood degree sum based topological indices is neighborhood M-polynomial. The bismuth tri-iodide 𝐵𝑖𝐼3 is a wide band gap layered semiconductor with several optical properties.In this paper, the neighborhood M-polynomial of bismuth tri-iodide chain and sheet are obtained. Some topological indices based on neighbourhood degree sum are recovered from the neighbourhood Mpolynomial. Also, the findings are interpreted graphically.
