Abstract:
1. A method of fabricating nanotube structures comprising the steps of: providing a substrate with a surface; providing a first photoresist layer positioned on the surface of the substrate; providing a second photoresist layer positioned on the first photoresist layer; patterning and etching through the first and the second photoresist layers to form a first trench and a second trench wherein the first trench is spaced apart from the second trench by the first photoresist layer and the second photoresist layer; depositing a first conductive material layer on the surface of the substrate within the first trench and depositing a second conductive material layer on the surface of the substrate within the second trench; depositing a nanoparticle catalyst suspended in water onto at least one of the first conductive material layer and the second conductive material layer; removing the first photoresist layer and the second photoresist layer and subsequent layers deposited thereon; forming at least one nanotube with a first end and a second end using a reaction chamber; and wherein the first end of the at least one nanotube is connected to the first conductive material layer and the second end of the at least one nanotube is connected to the second conductive material layer.
