The Attitude of Variation of Elastic Modules in Single Wall Carbon Nanotubes: Nonlinear Mass-Spring Model
The examination of variation of elastic modules in single wall carbon nanotubes (SWCNTs) is the aim of this paper. Full nonlinear spring-like elements are employed to simulate specific atomic structures in the commercial code ABAQUS. Carbon atoms are attached to each node as a mass point using atomic mass of carbon atoms. The influence of dimensions such as variation of length, diameter, aspect...
متن کاملOptoelectronic properties of single-wall carbon nanotubes.
Single-wall carbon nanotubes (SWCNTs), with their uniquely simple crystal structures and chirality-dependent electronic and vibrational states, provide an ideal laboratory for the exploration of novel 1D physics, as well as quantum engineered architectures for applications in optoelectronics. This article provides an overview of recent progress in optical studies of SWCNTs. In particular, recen...
متن کاملOptical Properties of Single-Wall Carbon Nanotubes
Four kinds of single-wall carbon nanotubes (SWNTs) with different diameter distribution have been synthesized and optical absorption spectra have been measured. Three large absorption bands due to the optical transitions between spike-like density of states, characteristics of SWNTs, were observed from infrared to visible region. Comparing with the calculated energy band, it has been concluded ...
متن کاملA critical assessment of the elastic properties and effective wall thickness of single-walled carbon nanotubes.
This paper discusses the fundamental issues of the elastic properties and effective wall thickness of single-walled carbon nanotubes (SWCNTs). It provides an in-depth analysis based on the rationale of the nanoscale-to-macroscale deformation relationship of SWCNTs and carries out a critical assessment of the diverse theoretical predictions in the literature. It was found that the in-plane stiff...
متن کاملTheoretical Elastic Properties of Single Walled Carbon Nanotubes
Carbon fiber nanotubes are a relatively new material with amazing physical and electrical properties. In this paper we report the results of the first-principles calculations for the elastic properties of several single-wall carbon nanotubes (SWNT) with diameters between 4 and 17 !. We show that the torsional and axial strain potential energy curves can be well described in terms of the experim...
