Theory of Multi-tube Carbon Nanotube Transistors for High Speed Variation-Tolerant Circuits

In this paper, a multi-tube transistor (MTx) structure is proposed to reduce the burden of technology development for fabricating perfectly ordered array of nanotubes. The proposed MTx architecture accounts for variations and non-idealities that occur in CNFETs. MTx with short transistor channel length operates differently from the long channel CNT-based TFTs where the carriers hop from tube to tube in a percolation network.
