investigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولElectrical and Structural Properties of Carbon Nanotubes
The rapid progress of interest in carbon nanotubes research have been improved with a development of sensitive tools for their observation and characterization. In this work Raman spectroscopy and atomic/electric force microscopy (AFM/EFM) have been successfully applied for studying electrical and structural properties of multiwall carbon nanotubes (MWNT). The combination of these methods (Rama...
متن کاملStructural Properties of Graphene and Carbon Nanotubes
Graphene was discovered in 2004 and has since sparked much interest in the field of condensed matter physics. Graphene is an atomically thin sheet of carbon arranged in a two dimensional honeycomb crystal. The MerminWagner Theorem predicts that a perfect crystal can not exist in two dimensional space, so it was surprising when graphene was first observed[1]. The existence of graphene has since ...
متن کاملCarbon Nanotubes – A scientometric study
In contrast to our previous study (Barth & Marx, 2008) dealing with a currently decreasing research field (high-temperature superconductors) we analyzed here a topic which has raised a strongly increasing interest among researchers: research activities around carbon nanotubes (CNTs or NTs). Carbon nanotubes (often named only nanotubes) are graphite sheets rolled up into cylinders with diameters...
متن کاملStructural Mechanics Approach to Investigate the Hyperelastic Mechanical Behavior of Single and Multi-wall Carbon Nanotubes
In the current research, a three-dimensional finite element model was considered to predict the mechanical behavior of Single Wall (SWCNTs) and Multi Wall Carbon Nanotubes (MWCNTs). Assuming the nonlinear elastic behavior of C-C bond in large strains, hyperelastic models were considered. Literature review revealed that the material parameters of the hyperelastic models have been determined from...
