Abstract
Nanotechnology enables us to use new nano material such as Carbon
Nanotubes (CNT) to build devices enormously smaller with better performance, thus
bringing fundamental changes to the disciplines including engineering, chemistry,
medicine, biology, and physics. Using 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), fast response time, and high dynamic ranges. Most importantly,
it can make infrared detection in different spectrums at room temperatures. This
unique feature can significantly reduce the size and weight of an infrared imaging
system by eliminating cryogenic cooling. Furthermore, the fast response time of a
CNT based infrared detector has made it possible for us to use compressive sensing
method to develop infrared imaging systems. In this presentation, the issues related
to the design and manufacturing of CNT based infrared detectors will be discussed.
Theoretical foundations as well as implementation schemes for the development of
integrated nanomanufacturing systems for fabricating CNT based IR detectors will
be presented. Specific topics include nano robotic tools for manipulation and
assembly, nano material purification and delivering processes, as well as nano
device packaging and testing. In addition, a new CNT based IR imaging system will
be discussed. In particular, the experimental testing results will be presented
highlighting the capability of the new IR imaging system in achieving superb
performance enabled by CNT based IR detectors.
