Abstract

We report the growth and detailed structural investigation of a new morphological manifestation of carbon-based nanostructures in the form of tapered whiskers with uniform 1-3 nm hollowness. The base of the whiskers is in the submicron scale, tapering uniformly to form a pointed tip in the form of a pipette. These hollow nanopipettes have a shell containing helical graphitic sheets. We propose that these whiskers grow by competing phenomena of growth and etching that control their aspect ratio.
