Self-aligned growth of carbon nanosticks

Pulsed laser deposition of carbon on LiNbO3 as substrate material leads for certain process parameters to the growth of self-aligned carbon stick-like nanoparticles (so called nanosticks). The carbon nanosticks and the growth conditions were investigated in detail by means of atomic force microscopy, scanning electron microscopy and conductivity measurements. A model for the growth mechanism is presented on the basis of the experimental investigations.
