Abstract

Carbon nanotube (CNT) has been found to be one of the promising semiconducting materials for nanoelectronic sensors due to its unique electrical properties. Our group has developed a spectrum sensor using a single CNT and demonstrated its performance. In this paper, a steady and high-yield CNT band gap engineering will be developed and used to manufacture an appropriate CNT for infrared (IR) detection. The fabrication and experimental result of the CNT-based spectrum sensor will be presented. The results indicate that the CNT-based spectrum sensor is capable to sense near IR and middle-wave IR signals at room temperature. © 2009 American Institute of Physics.
