ABSTRACT=<p>We have used the envelope function formalism to investigate the bands structure of LWIR type II SL InAs (d<sub>1</sub> = 2. 18d<sub>2</sub>)/In<sub>0.25</sub>Ga<sub>0.75</sub>Sb(d<sub>2</sub> = 21.5 Å). Thus, we extracted optical and transport parameters as the band gap, cut off wavelength, carriers effective mass, Fermi level and the density of state. Our results show that the higher optical cut-off wavelength can be achieved with smaller layer thicknesses. The semiconductor-semi metal transition was studied as a function of temperature. Our results permit us the interpretations of Hall and Shubnikov-de Haas effects. These results are in agreement with experimental results in literature and a guide for engineering infrared detectors.</p>
