Abstract: This paper reports on electrical and electro-optical characterizations of Ga-free InAs/InAsSb type-II superlattices (T2SL) midwave infrared barrier photodetectors grown by Molecular Beam Epitaxy on GaSb substrate. Experimental measurements are made of photo-response and dark current density-voltage (J-V) measurements performed as a function of temperature and transport of minority carrier in this barrier detector is discussed. Results obtained at 150 K for 5µm cut-off wavelength are at the state of the art but identification of an high bias voltage operation demonstrates that the barrier layer has to be improved.
