About the Event

Using carbon nanotubes (CNT), we have developed high performance infrared detectors. Since the CNT has extraordinary optoelectronics properties due to its unique one dimensional geometry and structure, the CNT based infrared detectors have extremely low dark current, low noise equivalent temperature difference (NETD), high response time, and high dynamic range. Most importantly, it can detect 3-5 um middle-wave infrared (MWIR) at room temperature. This unique feature can significantly reduce the size and weight of a MWIR imaging system by eliminating a cryogenic cooling system. In this presentation, the issues related to the design and manufacturing of CNT based infrared detectors will be discussed. The theoretical foundations as well as the implementation schemes for the development of integrated nanomanufacturing systems for fabricating CNT based IR detectors will be presented. The topics will include the nano robotic tools for manipulation and assembly, nano material purification and delivering processes, as well as nano device packaging and testing. Furthermore, the design of a new CNT based IR imaging system will be presented. The experimental testing results show that the new IR imaging system can achieve the superb performance enabled by CNT based IR detectors, and, at same time, to achieve high resolution and efficient imaging.
