Abstract

An aggregate of carbon-based fine structures in which a plurality of carbon-based fine structures are collected, wherein respective carbon-based fine structures are oriented in the same direction. The above aggregate of carbon-based fine structures is an aggregate of a plurality of carbon-based fine structures in a state they are pulled by one another with strong interaction, and has such a length that allows the improvement of the handeability and workability thereof.

First claim

The invention claimed is:

1. An array of carbon-based microstructures, comprising:
carbon nanotubes on a substrate aligned substantially perpendicular to the substrate,
wherein the carbon nanotubes are on the substrate at a density of no less than 1×10 11 /cm 2 ,
at least one of the carbon nanotubes has a diameter of no more than 20 nm, and
at least one of the carbon nanotubes has a length of 52 μm through 170 μm.

2. An array of carbon-based microstructures as set forth in claim 1 , wherein the carbon nanotubes include no greater than 10 bends per 1 μm length extending in the direction of alignment,
wherein the bends are portions of the carbon nanotubes that are bent as a result of defects occurring in the presence of crystal arrangement other than six-membered rings of carbon atoms.

3. The array of carbon-based microstructures as set forth in claim 1 , wherein the at least one of the carbon nanotubes has a length of 52 μm through 160 μm.

4. The array of carbon-based microstructures as set forth in claim 1 , wherein at least one of the carbon nanotubes has a diameter of no less than 10 nm.

5. The array of carbon-based microstructures as set forth in claim 1 , wherein the at least one of the carbon nanotubes has a length of 160 μm through 170 μm.

6. An array of carbon-based microstructures, comprising:
a substrate and;
carbon nanotubes on the substrate aligned substantially perpendicular to the substrate,
wherein the carbon nanotubes are on the substrate at a density of no less than 1×10 11 /cm 2 ,
at least one of the carbon nanotubes has a diameter of no more than 20 nm; and
at least one of the carbon nanotubes has a length of 52 μm through 170 μm.

7. The array of carbon-based microstructures as set forth in claim 6 , wherein at least one of the carbon nanotubes has a diameter of no less than 10 nm.

8. The array of carbon-based microstructures as set forth in claim 6 , wherein the at least one of the carbon nanotubes has a length of 52 μm through 160 μm.

9. The array of carbon-based microstructures as set forth in claim 6 , wherein the at least one of the carbon nanotubes has a length of 160 μm through 170 μm.
