2-DIMENSIONAL ANIMAL-LIKE FRACTALS IN THIN-FILMS

We present a few unique animal-like fractal patterns in ionized-cluste r-beam deposited fullerene-tetracyanoquinodimethane thin films. The fr actal patterns consisting of animal-like aggregates such as ''fishes'' and ''quasi-seahorses'' have been characterized by transmission elect ron microscopy. The results indicate that the small aggregates of the animal-like body are composed of many single crystals whose crystallin e directions are generally different. The formation of the fractal pat terns can be attributed to the cluster-diffusion-limited aggregation.
