Abstract: An ultra-thin highly electrically conductive material is prepared by depositing an amorphous material, substantially free of crystal growth-inducing nuclei and sites, onto a substrate. Deposition is preferably with a plasma deposition reactor, with semiconductor dopants introduced during deposition. Deposition time is preferably adjusted to create an amorphous film of a desired thickness, e.g., 200 Å. After deposition, the amorphous film is annealed preferably with a rapid thermal annealing process for four minutes at 700° C. The annealing triggers the creation of nuclei and subsequent large grain growth in the film, releases energy contained within the amorphous material, and helps drive crystallization and dopant activation. After annealing the material is completely crystallized, and contains large grains whose lateral dimensions can exceed the film thickness by a factor of fifty.

Abstract: Hydrodegradable polyesters based upon the random copolymerization of aromatic and absorbable aliphatic polyesters are disclosed. The hydrodegradable polyesters are useful in preparing a variety of products including disposable containers, disposable diapers, fishing lines and nets, and the like.
