Abstract

An apparatus, system, and method are provided for a vertical two-terminal nanotube or microtube device configured to capture and generate energy, to store electrical energy, and to integrate these functions with power management circuitry. The vertical device can include a column disposed in a template material extending from one side of the template material to the other side of the template material. Further, the device can include a first material disposed within the column, a second material disposed within the column, and a third material disposed in the column. A variety of configurations, variations, and modifications are provided.

First claim

We claim:

1. A vertical nanotube device, comprising:
a columnar pore disposed in a template material extending as a column all the way from a first side of the template material to a second side of the template material;
at least one material formed as a nanotube or nanowire within the columnar pore,
wherein the vertical nanotube device is perpendicular or substantially perpendicular to a substrate of the vertical nanotube device.

2. The vertical nanotube device of claim 1 , further comprising:
electrolyte disposed within the column inside the at least one material.

3. The vertical nanotube device of claim 2 , wherein the at least one material is formed in a discontinuous pattern having a separation region between at least one first segment of the at least one material and at least one second segment of the at least one material, wherein the electrolyte is disposed at least within the separation region.

4. The vertical nanotube device of claim 2 , wherein the electrolyte comprises a liquid electrolyte.

5. The vertical nanotube device of claim 2 , wherein the electrolyte comprises a gel electrolyte.

6. The vertical nanotube device of claim 2 , wherein the electrolyte comprises a solid electrolyte.

7. The vertical nanotube device of claim 2 , further comprising:
first and second current collectors configured to contain the electrolyte within the column.
