Abstract

We demonstrated the coating of carbon nanotubes (CNTs) with compound ultrathin films towards functional SPM tips. Conductive, ferromagnetic, and uperconducing materials were uniformly coated around isolated multi-walled CNTs (MWNTs). As a conductive probe, the CNT glued on a W tip was wholly coated with a thin PtIr layer 6 nm thick. The current-voltage characteristics of the resultant PtIr-coated CNT tips indicated that the PtIr coating stably reduced the resistance between the CNT tip end and the W supporting tip. Our method will facilitate the development of family of novel functional scanning probe microscopies (SPMs) using CNT tips. [DOI: 10.1380/ejssnt.2005.417]
