Abstract
We have proposed the method to obtain high effective quantum efficiency in uncooled LWIR HgCdTe photodiodes. We have designed the stacked multi junction photodiodes working in non-equilibrium conditions. The effective quantum efficiency being the product of quantum efficiency and photoelectrical gain can achieve significant values, much greater than 100%, when the structure is reverse biased.
