ABSTRACT

This paper presents reduction of crosstalk in CNT bundle interconnects using different innovative strategies. First, we propose the use of semiconducting CNTs (s-CNTs) as electromagnetic interference (EMI) shields for CNT bundle interconnects. We compute the coupling capacitance of the proposed CNT bundle structure which shows that the crosstalk can be reduced significantly by using s-CNTs. Next, we propose a novel geometry for CNT bundles that can reduce the coupling between adjacent CNT bundle interconnects. The proposed geometry can make CNT interconnects perform 46% better in terms of crosstalk induced delay than traditionally proposed square CNT bundles.
