Infrared Super Lattice Detectors from VIGO (2-12 µm)
VIGO has launched first Super Lattice test detectors based on a InAs / InAsSb structure. A superlattice itself is a system of very thin layers of two materials with thicknesses of several nm. In the material manufactured in such a way an energy gap can be freely tuned which means that, for example, by changing the layert thickness ratio, one can contol the spectral range in which the material can detect radiation.
