摘要

碳纳米管（CNTs）是碳原子排列在六边形晶格中的管状纳米形式，结的形成赋予了这些管新的功能。在各种类型中，将单个碳纳米管分裂成y形结构的y结，由于其特殊的结构和电子特性，在纳米电子学和逻辑器件中具有特别重要的意义。在这项工作中，使用化学图论计算了四种碳纳米管y结的Balaban， Forgotten和Zagreb指数。结果清楚地表明，所有这些拓扑指标在不同构型的y型结中逐渐增加，这证明了结构的复杂性和稳定性与其电子性质之间的直接关系。

Topological indices and their correlation with structural properties of carbon nanotube Y-junctions

Carbon nanotubes (CNTs) are tubular nanoforms of carbon atoms arranged in a hexagonal lattice, and junction formation imparts new functionalities to these tubes. Among the various types, Y-junctions, in which a single CNT splits into a Y-shaped structure, have particular importance in nanoelectronics and logic devices due to their special structural and electronic properties. In this work, the calculation of the Balaban, Forgotten, and Zagreb indices for the four types of CNT Y-junctions is carried out using chemical graph theory. The obtained results clearly show that all these topological indices increase progressively across the different configurations of the Y-junctions, which evidences a direct relationship among the structural complexity and stability with their electronic properties.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
