We show that it is possible to construct low-noise single-electron transist
ors (SETs) using free-standing multiwalled carbon nanotubes. The 1/f(alpha)
-noise of our devices, 6x10(-6) e/root Hz at 45 Hz, is close in the perform
ance to the best metallic SETs of today. (C) 2001 American Institute of Phy
