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 ...

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

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 ...

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.
