Scattering Processes in Nanocarbon-Based Nanointerconnects

subject

description

Cluster approach based on the multiple scattering theory (MST) formalism, realistic analytical and coherent potentials as well as effective medium approximation (EMA–CPA) can be effectively used for nanosized systems modelling. Major attention is paid now to applications of carbon nanotubes (CNTs) and graphene nanoribbons (GNRs) with various morphology which possess unique physical properties in nanoelectronics, e.g. contacts of CNTs or GNRs with other conducting elements of a nanocircuit, which can be promising candidates for interconnects in high-speed electronics. The main problems connected with the resistance of C–Me junctions with metal particles appear due to the influence of chirality effects in the interconnects of single-walled (SW) and multiwalled (MW) CNTs and single-layered (SL) and multilayered (ML) GNRs with the fitting metals (Me = Ni, Cu, Ag, Pd, Pt, Au) for the predefined carbon system geometry. Using the models of ‘liquid metal’ and ‘effective bonds’ developed in the framework of the presented approach and Landauer theory, it is possible to predict resistivity properties for the considered interconnects. The model of the inter-wall interaction inside MWCNTs, which demonstrates possible ‘radial current’ losses, has been developed.
