Stability analysis of multilayer vertical graphene nanoribbon interconnects

Abstract

In this work, stability of lithium intercalation doped Multilayer Vertical Graphene Nanoribbon (ML-VGNR) interconnects is estimated and compared with existing copper and lithium intercalated Multilayer Horizontal Graphene Nanoribbon (ML-HGNR) interconnects. ML-VGNR interconnects have a sharp, well behaved transient response among all the interconnect configurations. An isolated copper interconnect has the highest stability but when crosstalk is considered, ML-VGNR interconnect is the most stable one. This work for the first time analyzes and compares the stability of ML-VGNR, ML-HGNR and copper interconnects on isolated, single interconnect and 3-interconnect configurations.
