Method of controlling supersaturated injection and concentration of exotic atoms into deep portions of a solid with a high energy electron beam

Claim 1

A method of controlling injection and concentration of exotic atoms into deep portions of a solid with an electron beam having high energy enough to cause supersaturation, comprising previously preparing a parent material having a face-centered cubic lattice by a fabricating method selected from among vapor depositing, sintering and clad rolling whereby exotic phases composed of exotic atoms are buried into predetermined places of parent phases composed of the parent material, irradiating the parent material with the electron beam having high energy enough to displace the atoms which compose the exotic phases and the parent phases at a temperature which is low enough to restrain thermal diffusion of the exotic atoms, whereby supersaturated injection regions of the exotic atoms are formed at the predetermined places in the parent phases.

Claim 2

A method of controlling injection and concentration of exotic atoms into deep portions of a solid with an electron beam having high energy enough to cause supersaturation, comprising previously preparing a parent material having a face-centered cubic lattice by a fabricating method selected from among vapor depositing, sintering and clad rolling whereby exotic phases composed of exotic atoms are buried into predetermined places of parent phases composed of the parent material, irradiating the parent material with the electron beam having high energy enough to displace the atoms which compose the exotic phases and the parent phases at a temperature which is low enough to restrain thermal diffusion of the exotic atoms, whereby supersaturated injection regions of the exotic atoms are formed at the predetermined places in the parent phases.

Claim 4

A method of injecting exotic atoms into deep parts of a solid with electron beams of high energy to produce regions supersaturated with exotic atoms, the method comprising: preparing a parent material having exotic phases consisting of exotic atoms of germanium or silicon in parent phases consisting of atoms of a metal having a face-centered cubic lattice by burying the exotic phases at predetermined places in the parent phases by a method selected from among vapor deposition, sintering, and clad rolling; irradiating the parent material with an electron beam and at a temperature which substantially restrains thermal diffusion, the electron beam having sufficient energy to displace both the atoms which constitute the exotic phases and the atoms which constitute the parent phases by collisions which propagate at a jump rate P.

Claim 5

A method of injecting exotic atoms into deep parts of a solid with electron beams of high energy to produce regions supersaturated with exotic atoms, the method comprising: preparing a parent material having exotic phases consisting of exotic atoms of germanium or silicon in parent phases consisting of atoms of a metal having a face-centered cubic lattice by burying the exotic phases at predetermined places in the parent phases by a method selected from among vapor deposition, sintering, and clad rolling; irradiating the parent material with an electron beam and at a temperature which substantially restrains thermal diffusion, the electron beam having sufficient energy to displace both the atoms which constitute the exotic phases and the atoms which constitute the parent phases by collisions which propagate at a jump rate P.
