  • Method for injecting exotic atoms into a solid with electron beams
    Patent number: 4670292
    Abstract: A method for injecting exotic atoms into a solid with electron beams comprises irradiating a material having structure of two layers to which at least one thin film adheres with electron beams, and injecting the exotic atoms into an irradiation region. This method gives desired forms such as crystal, noncrystal, solid solution of the materials, depending on the conditions of electron irradiation.

  • Method for amorphizing a material by means of injection of exotic atoms into a solid with electron beams
    Patent number: 4668527
    Abstract: A method for amorphizing a material comprises attaching a thin film consisting of exotic atoms to a parent material, irradiating the two layer material under given conditions of irradiation from the side of the thin film with electron beams, and injecting forcibly the exotic atoms into the parent material to change the material into an amorphous material. This method can produce amorphous materials having new functions.
