Defect controlled nanotube sensor and method of production

摘要

Sensor for detecting a physical or chemical quantity, comprising a defect controlled nanotube. The sensor can be produced by post treating a nanotube with sufficient energy to modify at least one of density and type of defects in the nanotube, and associating the nanotube with a circuit capable of providing an output signal based upon change of electrical characteristic of the nanotube in response to stimulus of the nanotube.
