Abstract

Graphyne-based nanotubes are cylindrical structures made up of a single layer of graphyne that has been rolled into a tube. These one-dimensional structures are constructed from carbon atoms with both sp and sp² hybridization. The common graphene-based carbon nanotubes, and graphyne-based nanotubes including α-, β-, γ-, α2-, 6,6,12-, and δ-graphyne nanotubes are introduced. The atomic structures and electronic characteristics of these tubes are reviewed. The electronic band structures and density of states calculated by density functional theory are presented. The nanotubes with different types and chiralities display either metallic or semiconducting characteristics. The variety of structures and electronic properties of these nanotubes make them extremely hopeful for applications, especially in nanoelectronic devices such as field emission transistors, sensors, nanoelectromechanical systems, super capacitors, energy and data storage devices.

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
