Carbon films are a type of fossil, or preservation. They are thin film coatings which consist predominantly of the chemical element carbon, which include plasma polymer films, amorphous carbon films (diamond-like carbon, DLC), CVD diamond films as well as graphite films. The soft tissues of organisms are made largely of organic carbon compounds. Sometime fossils contain only carbon. Fossils usually form when sediments bury a dead organism. As sediment piles up, the organism's remains are subjected to pressure and heat. These conditions force gases and liquids from the body. A thin film of carbon residue is left, forming a silhouette of the original organism called a carbon film.
Famous quotes containing the word film:
“Television does not dominate or insist, as movies do. It is not sensational, but taken for granted. Insistence would destroy it, for its message is so dire that it relies on being the background drone that counters silence. For most of us, it is something turned on and off as we would the light. It is a service, not a luxury or a thing of choice.”
—David Thomson, U.S. film historian. America in the Dark: The Impact of Hollywood Films on American Culture, ch. 8, William Morrow (1977)
