A method for processing one-dimensional nano-materials includes the following
steps:
providing a substrate (11); forming one-dimensional nano-materials (12)
on the substrate, the one-dimensional nano-materials being substantially parallel
to each other and each being substantially perpendicular to the substrate, the
one-dimensional nano-materials cooperatively defining a top surface distal from
the substrate; and applying physical energy (14) by means of a high-energy
pulse laser beam to the top surface of the one-dimensional nano-materials. The
resulting one-dimensional nano-materials have sharp, tapered tips (15, 15).
Distances between adjacent tips are approximately uniform, and are relatively large.
This reduces shielding between adjacent one-dimensional nano-materials. The tips
also contribute to a decreased threshold voltage required for field emission by
the one-dimensional nano-materials.
