Molecular electronics: Built on columns

Anne Pichon

The size and conducting properties of single-wall carbon nanotubes (SWNTs) make them attractive building blocks for nanoelectronic devices. SWNTs have successfully been exploited in various molecular electronic systems — instead of metal electrodes — circumventing problems associated with gold–thiol junctions.
