AbstractCarbon nanotube (CNT) has been found to be one of the promising materials for efficient detection and used in different nanoelectronic devices due to its unique electrical properties. Recently, the applications of nanostructural material to infrared (IR) sensors are considered. Our group developed a color detector using a single CNT and demonstrated the good sensitivity of CNT to the infrared light in different ranges. In this report, the CNT bandgap engineering was discussed. The design, fabrication and experimental result of the CNT based color detector were described. The results indicated the heterogeneous electrode structure increased the signal-to-dark current ratio. Moreover, the CNT based color detectors were capable to sense near-infrared signal and middle-infrared signal in room temperature environment.
