Nanotube Chirality

Carbon nanotube thin films are considered by many researchers as a material for the future in many electrical and thermal applications, but a lack of systematic physics-based modeling approaches to quantify the bulk thermal and electrical response due to nanostructure variations makes employing these thin films difficult for commercial applications. In this work we employ the previously presented 3D physics-based computational model for characterizing the bulk thermal and electrical response of a neat carbon nanotube thin film network involving stochastic distributions of length, diameter, chirality, orientation and values of intercontact resistivity obtained from the literature. The model is employed to test the sensitivity of bulk thermal and electrical conductivity on stochastic variations in the nanostructure parameters. We examine the sensitivity of the thin film networks to the experimentally obtained Weibull probability distribution for length and diameter. Additionally, we present a study to quantify the macroscopic conductivity dependence on the nanotube chirality ratio. Through these studies we present an approach that is very generic and can be used for the sensitivity analysis due to variations within the nanostructure.

Nanotube Chirality

This Paper presents the design and simulation of single walled carbon nanotube (SWCNT) based cantilever type electrostatic actuator using finite element analysis method (FEM). The pull-in voltage has been calculated for various chirality of the nanotube based cantilever beam actuators. The pull-in voltage are obtained for the various gap between electrode and ground of the cantilever beam through extensive simulations using ANSYS software. The results obtained shows that pull-in voltages varies from 2.5 to 13.5V with respect to nanotube chirality and gap length.

In this paper, using the non-equilibrium Green's function formalism (NEGF), the effect of the chirality of carbon nanotube (CNT) on the performance of the strained tunneling carbon nanotube field effect transistors (T-CNTFETs) has been investigated. In this work, all evaluations are done by this assumption that the ON current, I ON , is the main performance metric in the T-CNTFETs. The uniaxial strain has been considered in this work. On the other hand, for constructing a transistor with a desired I ON , a variety of CNTs with the appropriate uniaxial strain could be used. The results of doing some comparisons among these situations show that, the use of the small diameter CNTs with the appropriate uniaxial strain could lead to the transistors with the better switching behavior. Likewise, the use of the large diameter CNTs with the appropriate uniaxial strain could result to the transistors with a higher I ON /I OFF ratio.
