Liquid gallium drops placed on thick Ag films at room temperature spontaneously form faceted nanoneedles of alloy oriented nearly normal to the surface. This observation suggests that single nanoneedles can be selectively grown by drawing silver-coated microcantilevers from gallium. Needles from 25 nm to microns in diameter and up to long were grown by this method. These metal-tipped cantilevers have been used to perform atomic force microscopy (AFM) and AFM voltage lithography.

The tip is manipulated using a manually controlled three-axis Fullam micromanipulator that is mounted through the chamber wall of the SEM. The use of the micromanipulator and the vacuum environment of the SEM is not a necessity, but is only used to observe the process and record the images for this paper.

Silver is sputtered to a thickness of 300 nm on a glass slide. Gallium is spread over the entire sample and then immediately placed in the x-ray diffractometer with the measurement being completed within an hour.

SAD was performed in a transmission electron microscope (TEM) at normal incidence to the grid and needle. The needle was grown on an ultrathin carbon, 400 Cu mesh TEM grid (Pelco). A sub-10-nm Cr adhesion layer and a 50 nm layer of Ag were sputtered on the grid. A small drop of Ga placed on the film reacted for several days to produce a sparse pattern of needles that could be probed individually by the TEM beam.
