摘要：

We investigate electrical transport,and noise m semiconducting carbon nanotubes. By studying carbon nanotube devices with various,diameters, and contact metals, we show that the,ON-currents of CNFETs are governed by the heights of the Schottky barriers at the metal/nanotube interfaces. The current fluctuations are dominated by 1/f noise at low-frequencies and correlate with the number of transport carriers in the device regardless of contact metal. (c) 2006 Elsevier B.V.
