Carbon Nanotube Circuits: Technology and Challenges

This lecture introduces the technology behind Sasha, a Carbon Nanotube Control Hand Shaking Robot, focusing on the promise, opportunities, and challenges facing carbon nanotube circuits. It covers the basics of carbon nanotubes, the formation of CNFETs, circuit design, obstacles like misposition and metallic CNTs, and solutions like imperfection immune design and VMR. The lecture showcases the first complete subsystem made of CNFETs, a capacitive sensor interface used to control Sasha, demonstrating the potential of CNFETs in achieving high energy efficiency. It also discusses the challenges of achieving high-performance circuits and the interesting design considerations for CNT circuits.
