Carbon Nanotubes from Lab to Fab

It is now widely appreciated that electronic devices based on carbon nanotubes (CNTs) have the potential to outperform conventional silicon devices. As the challenges associated with scaling silicon technology mount, CNTs are being seriously considered as an alternative, or successor, to silicon in high-performance logic applications. However, in order to create a viable high-performance CNT technology, daunting and unique integration challenges must be overcome. These include isolation of semiconducting CNTs, selective placement of CNTs from solution, and passivation. In this talk I will describe recent progress, made at IBM and elsewhere, on solving these challenges. I will highlight the device performance requirements for a competitive CNT technology, which guides our integration strategy. Finally, I will discuss the areas where fundamental research is needed in order to improve device performance.
