Abstract

Carbon nanotube template arrays may be edited to form connections between proximate nanotubes and/or to delete undesired nanotubes or nanotube junctions.

Claims (26)

1. A carbon nanotube (CNT) circuit template, comprising:

a plurality of CNTs comprising:

a first selected CNT;

a second selected CNT arranged at a selected angle to the first selected CNT; and

a removable intermediate layer interposed between the first selected CNT and the second selected CNT, the removable intermediate layer including at least one of a resist composition or a resist material, the at least one of a resist composition or a resist material configured for localized removal,

characterized in that the first selected CNT and the second selected CNT are selected to form a junction having a selected electrical property when placed in contact at the selected angle.

2. The CNT circuit template of claim 1 , wherein the removable intermediate layer is characterized in that at least a portion of the removable intermediate layer is removed by applying a first voltage to the first selected CNT and a second voltage to the second selected CNT.

3. The CNT circuit template of claim 1 , wherein the removable intermediate layer is characterized in that at least a portion of the removable intermediate layer is removed by a process including exposing the removable intermediate layer to electromagnetic energy.

4. The CNT circuit template of claim 3 , wherein the process further includes exposing the removable intermediate layer to a developer composition.

5. The CNT circuit template of claim 1 , wherein the removable intermediate layer is characterized in that at least a portion of the removable intermediate layer is removed by a process including exposing the removable intermediate layer to an electron beam or ion beam.

6. The CNT circuit template of claim 5 , wherein the process further includes exposing the removable intermediate layer to a developer composition.

7. The CNT circuit template of claim 1 , wherein the first selected CNT is metallic.

8. The CNT circuit template of claim 7 , wherein the second selected CNT is metallic.

9. The CNT circuit template of claim 7 , wherein the second selected CNT is semiconducting.

10. The CNT circuit template of claim 1 , wherein the first selected CNT is semiconducting.

11. The CNT circuit template of claim 10 , wherein the second selected CNT is metallic.

12. The CNT circuit template of claim 10 , wherein the second selected CNT is semiconducting.

13. The CNT circuit template of claim 1 , wherein the first selected CNT and the second selected CNT are at substantially a right angle.

14. The CNT circuit template of claim 1 , wherein the created junction would exhibit a nonlinear current-voltage response.

15. The CNT circuit template of claim 1 , wherein the created junction would exhibit a linear current-voltage response.

16. A carbon nanotube (CNT) circuit template, comprising:

a plurality of CNTs comprising:

a first selected CNT;

a second selected CNT; and

a removable intermediate layer interposed between the first selected CNT and the second selected CNT, the removable intermediate layer including at least one of a resist composition or a resist material, the at least one of a resist composition or a resist material configured for localized removal,

characterized in that the first selected CNT and the second selected CNT join to create a junction upon removal of the removable intermediate layer.
