This paper introduces a simple method to selectively fabricate a single carbon nanotube (CNT) on an atomic force microscopy (AFM) tip by controlling the trigger threshold to adjust the amount of growth solution attached to the tip. The yield rate is over 93%. The resulting CNT probes are suitable in length, without the need for a subsequent cutting process. The CNT probe successfully scanned complex nanostructures with a high aspect ratio.
