Thermionic refrigeration at CNT-CNT junctions

Applied Physics Letters, 2016
Monte Carlo (MC) simulation is used to study carrier energy relaxation following thermionic emission at the junction of two van der Waals bonded single-walled carbon nanotubes (SWCNTs). An energy-dependent transmission probability gives rise to energy filtering at the junction, which is predicted to increase the average electron transport energy by as ...

COMPUTATIONAL STUDY OF A CNT-URACIL-CNT COMPOUND

Modern Physics Letters B, 2011
Density functional calculations were performed to investigate the properties of a combination of two representative carbon nanotubes by assistance of the atomic sites of uracil, which is the characteristic nucleobase of RNA. The obtained parameters indicated that the resulting compound exhibit new properties with respect to the original nanotubes and ...

Transport properties of CNT/oligosilane/CNT heterojunctions

Physica B: Condensed Matter, 2013
Abstract Combining the non-equilibrium Green's function formalism with density functional theory, the transport properties of nine CNT/oligosilane/CNT heterojunctions were systematically studied. We have found that the incorporation of oligosilane linkage to the carbon nanotube mouth could significantly tune the transport properties compared with the

Micro-Stress Transfer of CNT and CNT-Interface in CNT Reinforced Mg-Matrix Composites

Advanced Materials Research, 2011
The aim of the present paper is that, utilizing finite element method, considering the influence of different length of CNTs and different strength of interface to investigate the micro stress distribution of CNT reinforced magnesium matrix composite. When analyzing, the material character of magnesium is regarded as anisotropic.

Fabrication and characterization of Fe3O4/CNTs and Fe2N/CNTs composites

Journal of Electroceramics, 2006
By controlling the nitridation temperature, magnetic nanoparticles (Fe3O4and Fe2N) were attached to the carbon nanotubes (CNTs) to fabricate new Fe3O4/CNTs and Fe2N/CNTs composites with magnetic property from the same precursor. The attachment of tiny magnetic nanoparticles on CNTs is crucial for the formation of a homogeneous composite, which provides

The influence of CNTs on the thermoelectric properties of a CNT/Bi2Te3 composite

Carbon, 2013
Abstract CNT/Bi 2 Te 3 composites were prepared from composite powders in which CNTs were implanted in the Bi 2 Te 3 matrix powders by a novel chemical route. It was found that the fabricated composite had a microstructure of a homogeneous dispersion of CNTs in the Bi 2 Te 3 matrix due to interfacial bonding agents of oxygen atoms attaching to the

Heat Dissipation Mechanism at Supported CNT-CNT Junctions

Volume 1: Heat Transfer in Energy Systems; Theory and Fundamental Research; Aerospace Heat Transfer; Gas Turbine Heat Transfer; Transport Phenomena in Materials Processing and Manufacturing; Heat and, 2012
The thermal transport at the carbon nanotube (CNT) interfaces such as CNT-oxide and CNT-CNT junctions can significantly impact the device performance and reliability of nanotube network based thin-film transistors. For an example, the high electrical and thermal resistance at CNT junctions can cause hot spots, inefficient heat removal or even breakdown

CNTs and CNT/ZnO nanostructures for use as electron sources

2010 8th International Vacuum Electron Sources Conference and Nanocarbon, 2010
The paper presents the growth and optimization of carbon nanotube (CNT) and CNT/zinc oxide nanostructures to produce novel electron sources. The emitters studied in this project are based on regular array of vertically aligned 5 μm height and 50 nm diameter CNTs with a pitch of 10 μm.
