In recent years, research into thin films has been immense, scientists believing that the potential applications for the fine layers of chemicals to be monumental. Some thin films, for instance, show promise as semiconductors that can be formed into advanced computer chips, while others exhibit special magnetic properties that make them well suited for cutting edge memory storage systems. Certain thin films also acts as superconductors, carrying electric current without any resistance at some temperatures. The research efforts of many scientists have been focused upon making the films more practical and convenient to use. For instance, if magnetic thin films are successfully grown on semiconducting substrates, it may be possible to incorporate the unique magnetic properties of these systems directly into computer circuitry, which would be particularly useful for high-density magnetic storage devices and magnetic sensors.
