Fundamental electromagnetic properties of CNTs and GNRs nanostructures with functionalized atomic groups and their various interconnects with the essential concentration of 'dangling bonds' are very sensitive to local external perturbations. The induced changes of local electronic density of states lead to correlated changes of current and spin states. The cluster approach based on the multiple scattering theory as well as an effective medium approximation were used to model the dispersion law, electronic density of states, conductivity, etc. Multiple scattering problems were solved for nanostructures with radial and axial symmetry. Parametrical numerical simulations of conductivity using the formalism of Kubo-Greenwood were carried out for zig-zag (m,0), armchair (m,m) and chiral (m,n) CNTs. The sensitivity of conductivity to the local electronic density of states in CNTs with local impurities (N and B atoms) was demonstrated to be promising for nanosensors.

“…2,7 The basic equations of this approach are as follows: The multiple scattering problem of the system of clusters like the multiple scattering model of condensed matter is resolved by the calculations on fundamental properties of condensed medium described within the EMA, which provides the full-scale electronic structure calculations and gives electronic densities of states (EDOS) ρðEÞ, conductivities σðEÞ, and total energies E½ρðrÞ of embedded clusters.…”

As carbon nanotubes (CNT) and graphene nanostructures (GNR) constitute the basis of high-speed nanoelectronics and nanosensors, we examine the fundamental properties of various CNT-metal (Me), GNR-Me, and CNT-graphene interconnects. The cluster approach based on the multiple scattering theory as well as effective medium approximation were used to model the dispersion law, electronic density of states (DOS), and conductivity, etc. Multiple scattering problems were solved for nanostructures with radial (quantum dots) and axial (nanowires, nanotubes) symmetry. Interconnect capacitances and impedances have been evaluated in the GHz and THz regimes. Parametrical numerical simulations of conductivity were carried out for zig-zag ðm; 0Þ, armchair ðm; mÞ, and chiral ðm; nÞ CNTs, and the sensitivity of conductivity to the local electronic DOS in CNTs with local impurities (N and B atoms) was demonstrated. CNTs, CNT-Me, and GNR-Me based nanostructures are prospective nanosensor structures.

“…For individual application, it is necessary to develop nanodevices with various functions for the human body, particularly, for the control of health parameters, the enhancement of human abilities, and prosthetics. Another course of development of nanosensors, nanoactuators, nanotransducers, etc-is the creation of artificial systems such as artificial intelligence or artificial individual [2,3].…”

Real time polymer nanocomposites-based physical nanosensors: theory and modeling

Functionalized carbon nanotubes and graphene nanoribbons nanostructures, serving as the basis for the creation of physical pressure and temperature nanosensors, are considered as tools for ecological monitoring and medical applications. Fragments of nanocarbon inclusions with different morphologies, presenting a disordered system, are regarded as models for nanocomposite materials based on carbon nanoсluster suspension in dielectric polymer environments (e.g., epoxy resins). We have formulated the approach of conductivity calculations for carbon-based polymer nanocomposites using the effective media cluster approach, disordered systems theory and conductivity mechanisms analysis, and obtained the calibration dependences. Providing a proper description of electric responses in nanosensoring systems, we demonstrate the implementation of advanced simulation models suitable for real time control nanosystems. We also consider the prospects and prototypes of the proposed physical nanosensor models providing the comparisons with experimental calibration dependences.
