Neutralization of Carbon Nanotubes (CNTs) with Metallic Properties

AWARD:  $50,000 USD
DEADLINE: Withdrawn
POSTED: Apr 24 2012
SOURCE: InnoCentive

Carbon Nanotubes (CNTs) grown by Chemical Vapor Deposition statistically have 2/3 with semiconductor properties and 1/3 with metallic properties. We are looking for ways to remove or electronically neutralize CNT’s with metallic properties such that the CNT array acts as a semiconductor.

Challenge Overview

Carbon Nanotubes (CNTs) are grown by Chemical Vapor Deposition (CVD) on a substrate in a parallel array. Statistically, 2/3 have semiconductor properties and 1/3 have metallic properties. In order to make transistors, we are looking for new ways to remove or electronically neutralize the metallic nanotubes such that only the semiconductor tubes remain active. An alternative solution would be to grow CNT’s with only semiconductor properties. 

This is a Reduction-to-Practice Challenge that requires a written proposal and experimental proof-of-concept data (and/or sample delivery). 

The award is contingent upon theoretical evaluation and experimental validation of the submitted Solutions by the Seeker. 

To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution.  However, the Seeker will be willing to consider a licensingagreement for a partial award if exclusive IP cannot be transferred by the Solver. 

What is InnoCentive?

InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is an RTP Challenge?

An InnoCentive RTP (Reduction to Practice) Challenge is a prototype that proves an idea, and is similar to an InnoCentive Theoretical Challenge in its high level of detail. However, an RTP requires the Solver to submit a validated solution, either in the form of original data or a physical sample. Also the Seeker is allowed to test the proposed solution. For details about treatment of IP rights, please see the Challenge-Specific Agreement.
