Optimierte Eigenschaften von Quantumwell-Intersubband-Infrarotdetektoren - Photovoltaische Arbeitsweise gegenüber photoleitender Arbeitsweise
Abstract
A recently demonstrated transport mechanism giving rise to novel photovoltaic multiquantum well intersubband infrared detectors is analyzed theoretically. It is shown that optimized photovoltaic devices have detectivities that can be even larger than those of photoconductive ones. In addition, they have a high dynamic range and are particularly suited for the large photon fluxes occurring in the 8-12 mym regime.
