According to the ITRS Roadmap, on-chip interconnects wire width and current density will reach 22 nm and 5.8×106 A/cm2 in 2020, respectively. The electrical resistivity of Cu increases with scaled critical dimensions due to exacerbated carrier scattering at grain boundaries and interfaces, resulting in signal speed degradation. Electronmigration (EM)-related failure due to intensified current distribution posts extra limits to ultra-scaled systems. Innovative interconnect solutions are needed to tackle performance and scaling challenges.

Legacy Theses & Dissertations (2009 - 2024)
Apart from its compelling performance in conventional nanoelectronic device geometries, graphene is an appropriate candidate to study certain interesting phenomenon (e.g. the Veselago lens effect) predicted on the basis of its linear electron dispersion relation. A key requirement for the observation of such phenomenon in graphene and for its use in conventional field-effect transistor (FET) devices is the need to minimize defects such as consisting of - or resulting from - adsorbates and lattice non-uniformities, and reduce deleterious substrate effects. Consequently the investigation of the origin and interaction of defects in the graphene lattice is essential to improve and tailor …
