Abstract

original image

Get to know the onion: Conductance measurements for functionalized carbon nano-onions were conducted using an STM-based molecular junction approach (see picture). It was found that electron transmission through these systems occurs by a tunneling mechanism. The carbon-based core seems to provide a very efficient medium for electron transmission, with conductance values comparable to those of metallic nanowires.
