Abstract

A process for producing a carbon-particle structure, including the step of irradiating opaque carbon dioxide at and/or near its critical point, as light is scattered, with a UV-wavelength laser beam to produce a carbon-particle structure.

Claims

1. A process for producing a carbon-particle structure, comprising the step of irradiating opaque carbon dioxide at and/or near its critical point, as light is scattered, with a UV-wavelength laser beam to produce a carbon-particle structure.

2. The process for producing a carbon-particle structure according to claim 1, wherein the carbon-particle structure is produced on a substrate.

3. The process for producing a carbon-particle structure according to claim 1, wherein the carbon-particle structure has an amorphous structure.

5. The process for producing a carbon-particle structure according to claim 2, wherein the carbon-particle structure has an amorphous structure.

4. A process for producing a carbon-particle structure, comprising the steps of:

irradiating opaque carbon dioxide at and/or near the critical point, as light is scattered, with photons; and

colliding the photons with the carbon dioxide to produce the carbon-particle structure.

6. A process for producing a carbon-particle structure, comprising the steps of:

irradiating large molecule clusters of opaque carbon dioxide produced at and/or near the critical point, as light is scattered, with photons; and

colliding the photons with the opaque carbon dioxide having large molecule clusters to produce the carbon-particle structure.
