CNT Interconnects<br />
• Carbon nanotubes – CNTs – are sheets of<br />
graphite rolled into cylinders of diameters<br />
varying from 0.6 to about 3 nm<br />
• Demonstrate either metallic or semiconducting properties<br />
• depending on direction in which they are rolled<br />
• CNTs are promising candidates as on-chip interconnects<br />
• high mechanical and thermal stability<br />
• high thermal conductivity<br />
• large current carrying capacity<br />
• highly resistant to electromigration and other sources of breakdown<br />
• much better conductivity properties than Cu<br />
• due to longer electron mean free path (MFP) lengths in the micrometer<br />
range, compared to nanometer range MFP lengths for Cu
