This novel approach, using solution-processed perovskite, is intended to revolutionize a variety of everyday objects such as solar cells, LEDs, photodetectors for smart phones and...

 E-Mail Northwestern University researchers have developed a new approach to quantum device design that has produced the first gain-based long-wavelength infrared (LWIR) photodetector using band structure engineering based on a type-II superlattice material. This new design, which demonstrated enhanced LWIR photodetection during testing, could lead to new levels of sensitivity for next-generation LWIR photodetectors and focal plane array imagers. The work could have applications in earth science and astronomy, remote sensing, night vision, optical communication, and thermal and medical imagi...

But in recent years, a pan-European collaboration, in partnership with ...
