Abstract
A mechanically stable and oriented scanning probe tip comprising a carbon nanotube having a base with gradually decreasing diameter, with a sharp tip at the probe tip. Such a tip or an array of tips is produced by depositing a catalyst metal film on a substrate (in FIG.()), depositing a carbon dot (in FIG.()) on the catalyst metal film, etching away the catalyst metal film (FIG.()) not masked by the carbon dot, removing the carbon dot from the catalyst metal film to expose the catalyst metal film (FIG.()), and growing a carbon nanotube probe tip on the catalyst film (in FIG.()). The carbon probe tips can be straight, angled, or sharply bent and have various technical applications.
