Device for electrical characterization of molecules using CNT-nanoparticle-molecule-nanoparticle-CNT structure
A method of forming an electrode is disclosed. A carbon nanotube is deposited on a substrate. A section of the carbon nanotube is removed to form at least one exposed end defining a first gap. A metal is deposited at the at least one exposed end to form the electrode that defines a second gap.
1. A device, comprising:
a first carbon nanotube segment of a carbon nanotube disposed on a substrate, the first carbon nanotube segment having a first end;
a second carbon nanotube segment of the carbon nanotube having a second end, wherein the first end and the second end define a distance having a first length;
a first metal electrode deposited on the first end; and
a second metal electrode deposited on the second end, wherein the first metal electrode and the metal second electrode define a gap having a second length.
2. The device of claim 1 , wherein the first length is equal to a sum of the second length, a length of the first metal electrode, and a length of the second metal electrode.
3. The device of claim 1 , wherein the first length is greater than about 10 nanometers.
4. The device of claim 1 , wherein the second length is less than about 10 nanometers.
5. The device of claim 1 , wherein the first metal electrode and the second metal electrode define a molecular dock.
6. The device of claim 1 , wherein the first length is greater than about 10 nanometers and the second length is less than about 10 nanometers.
