Abstract
- Field-effect transistors (FETs) based on an individual CN[sub x]/C nanotube (NT) were fabricated by focus ion-beam technology. The nanotube transistors exhibited n-type semiconductor characteristics, and the conductance of nanotube FETs can be modulated more than four orders of magnitude at room temperature. The electron mobility of a CN[sub x]/C NT FET estimated from its transconductance was as high as 3.84×10[sup 3] cm[sup 2]/V s. The n-type gate modulation could be explained as due the effect of bending of the valence band in the Schottky-barrier junction. © 2003 American Institute of Physics. [ABSTRACT FROM AUTHOR]
