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