Abstract
A light detecting system is disclosed. The system comprises an arrangement of quantum dots forming an optically active region, a channel region and a charge carrier extractor between the active region and the channel region. The charge carrier extractor is characterized by a set of gradually decreasing energy levels between a characteristic excited energy level of the active region and a characteristic conductance energy level of the channel region.
