One of JAXA’s future missions, using an imaging Fourier Transform Spectrometer (FTS), requires the focal plane array (FPA) that has high sensitivity up to the very long-wavelength infrared (VLWIR) region. Since a Type-II superlattice (T2SL) is the

We report on the development of dual-band InAs/GaSb type-II strained layer superlattices (T2SL) detectors with barrier designs at SK Infrared. Over the past five years, we demonstrated mid-wave/long-wave (MW/LWIR, cut-off wavelengths are 5 μm and 10

Intermixing effect in type-II Ga 0.6 In 0.4 Sb/InAs superlattices is studied. The interdiffusion of both group- III and group V atoms across the heterointerface modifies the superlattices optical properties and electronic structures. The intermixed-i
