Vertical transport in narrow band gap antimonide based type-II strained layer superlattices T2SLs is a significant problem for the design of Mid-Wave Infrared MWIR, 3-5 m photodetectors. Investigation of the transport of electrons and holes in T2SLs is necessary to understand better how or if one can improve carrier collection efficiency through design or changes in material properties of this essential infrared absorber material. This report provides lateral and vertical transport results using magneto-transport for InAsSb alloys isotropic and InAsInAsSb T2SLs anisotropic. Then, vertical transport using EBIC technique will be discussed with results for InAsGaSb T2SL.
