摘要

This paper presents the development of non-cryogenic-cooling spectrum infrared (IR) detectors using a single Carbon nanotube (CNT). CNT has been found to be one of the promising materials for IR detection and used in different nanoelectronic devices due to its unique electrical properties. Here, the design, fabrication and experimental result of the CNT-based optical detectors are described. By developing the electrical breakdown process, the band gap of CNTs can be precisely adjusted and therefore, spectrum detectors can be obtained. The results indicate that CNTs are very sensitive in the near-IR (NIR) and middle-wave IR (MWIR) regions. Moreover, the temperature dependence of the detectors is studied. We demonstrate that CNT-based optical detectors can operate at room temperature.
