Article Summary

A new type of light sensor that acts like a pixel in a digital camera has been created by researchers at the University of Toronto. Scientists believe the sensor, which takes advantage of a phenomenon called multi-exciton generation (MEG), could lead to substantial advancements in the performance of a variety of electronic devices including digital cameras.
