Chirality Assignment: Band Gap Modification of Single- Walled Carbon Nanotubes with Strain
نویسندگان
چکیده
Single-walled carbon nanotubes (SWCNTs) offer a range of potential applications based on their unique one-dimensional structures. Theoretical calculations shows that their electronic structures depend strongly on their chiral vector indices (n,m) which determine the diameter and chiral angle. The graphite wrapping condition n-m=3p+q generates metallic tubes for q=0, while semiconducting tubes are found for q=+1 [1].

Coupled Axial-Radial Vibration of Single-Walled Carbon Nanotubes Via Doublet Mechanics
This paper investigates the coupled axial-radial (CAR) vibration of single-walled carbon nanotubes (SWCNTs) based on doublet mechanics (DM) with a scale parameter. Two coupled forth order partial differential equations that govern the CAR vibration of SWCNTs are derived. It is the first time that DM is used to model the CAR vibration of SWCNTs. To obtain the natural frequency and dynamic respon...
متن کاملEffect of strain on the band gap and effective mass of zigzag single-wall carbon nanotubes: First-principles density-functional calculations
We have studied the behavior of band gap and effective mass of both the electrons and the holes in small diameter zigzag single-walled carbon nanotubes under uniaxial mechanical strain by using first-principles density-functional theory. The band gap of these nanotubes is modified by both compressive and tensile strain and all zigzag single-wall carbon nanotubes show a semiconductor-metal trans...

Determination of the mechanical properties of carbon nanotubes is an essential step in their applications from macroscopic composites to nano-electro-mechanical systems. In this paper we report the results of a series of molecular dynamics simulations carried out to predict the elastic constants, i.e. the elements of the stiffness tensor, and the elastic moduli, namely the Young’s and shear mod...
