Abstract
The germanium (Ge) films of nanostructures deposited at 300 and 77 K by the cluster-beam evaporation technique are found to consist of small nanostructures. The crystal structure of the films is not the ordinary diamond but tetragonal structure. The Ge film deposited at 77 K exhibits photo-oxidation and blue-light emission when it is exposed to UV light. It may be said that the material possesses an ability to sense the environment and change in response to a change in the environment, which is one of the functions of intelligent materials. It, however, never restores itself even if an external stimulus (UV light in this case) is removed. Nevertheless, because of the unique crystal structure and optical properties of the Ge films, there is a possibility that further study may reveal their potential for intelligent materials.
