43.1  INTRODUCTION

Carbon nanotubes are hollow cylinders in which carbon atoms are arranged in the honeycomb lattice [1]. They were first demonstrated by Bethune [2] and Iijima [3] in 1993. Carbon nanotubes have found numerous applications in nanoelectronics because of their superior electronic properties.

Single-walled carbon nanotube field-effect transistors (CNFETs) ...
