| Abstract | Metallic carbon nanotubes (CNTs) have received worldwide attention as potential substitutions for traditional vertical interconnect (via) materials due to their excellent inherent electrical and thermal properties. In this paper, we present a RLC transmission line model for a single single-walled CNT (SWCNT) via. The resistance of a CNT is dependent on both the magnitude of the applied bias voltage and its length. Due to the low-bias nature of via application, weak electron scattering (acoustic phonons) dominates and the electron mean free path can be as large as a few micrometers. For 1-D nanoelectronic systems, the kinetic (or quantum) inductance dominates the magnetic (or continuum) inductance. As the CNT via is designed to be shielded by a grounded ring, the electrostatic capacitance between the via and the ring is considered. Subsequently, this single SWCNT model is further developed to include a bundled SWCNT via as a result of the weak intertube coupling. Established theoretical modeling results and experimental findings conclude that only the outer tube of the multi-walled CNT (MWCNT) contributes to its conductance. From this, we infer that our modeling approach can also be used for predicting the performance of single and bundled MWCNT-based vias. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
