Abstract

We present the development of a single carbon nanotube (CNT) based optical detector in the infrared (IR) region. CNTs have been found to be sensitive under IR radiation and they could be used as IR sensing elements. When a CNT is manipulated between two metal electrodes, two contacts are formed at the CNT-metal interfaces. The contact conditions play an important role in IR detection. Current results indicated that asymmetric electrode is capable to maximize photocurrent. The optical response time of the devices was also measured and considered. Beside, a reliable and efficient nano-manufacturing process has been introduced to build CNT-based IR detector. As a result, high efficiency, high sensitivity, stable and reliable performance CNT-based IR detectors can be fabricated. © 2009 IEEE NANO Organizers.
