The principles of charge carrier transport developed for Si-based devices must be reconsidered for SWCNT-based devices due to the reduced dimensionality of the metal–SWCNT interface. In this review, the technological progress in the improvement of the

• at metal–SWCNT interface When a metal and a semiconductor are brought into intimate contact, the electric charges are redistributed to reach equilibrium at the metal–semiconductor interface due to the difference in their material work functions. Because of the charge redistribution, a Schottky
