Carbon Nanotube Field Effect Transistors Development and Perspectives
A. Benfdila

The present paper treats the Carbon Nanotube Field Effect Transistors (CNFETs) in terms of new development as a possible future basic element for beyond CMOS technology used in ultra high scale integration ULSI. The CNFET is studied both in physical as well as technological point of views aiming a further understanding of the limitations to high integration density.

The different types of carbon nanotubes (SWNT) and (MWNT) used for electronic and sensing devices are discussed and the limitations for a higher integration density are evidenced. The CNFET switching characteristics and the IV characteristics are discussed to evidence the power dissipation and the switching frequency.

Keywords: Carbon nanotubes, CNFET, integrated circuits, I-V characteristics, NanoMOSFET
