Abstract

On page 238, S. Wang, L.-M. Peng, and co-workers demonstrate the potential for constructing IR imaging systems based on solution-processed carbon nanotubes (CNTs). The inside cover depicts a part of the 150×150 detector array, showing a typical cascading photodetector with two virtual contacts, which can greatly increase the signal-to-noise ratio and therefore improve light detection. Compared with traditional IR systems, detectors based on solution-processed CNTs are simpler to fabricate, lower cost, and much more stable.
