Abstract: Thanks to their wavelength diversity and to their excellent uniformity,Quantum Well Infrared Photodetectors QWIP emerge as potential candidates forastronomical or defense applications in the very long wavelength infraredVLWIR spectral domain. However, these applications deal with very lowbackgrounds and are very stringent on dark current requirements. In this paper,we present the full electro-optical characterization of a 15 micrometer QWIP,with emphasis on the dark current measurements. Data exhibit striking features,such as a plateau regime in the IV curves at low temperature 4 to 25 K. Weshow that present theories fail to describe this phenomenon and establish theneed for a fully microscopic approach.
