Abstract
Despite the preceding Comment's assertions, the maximum theoretical detectivities of LWIR InAs/ InGaSb superlattices are greater than those of HgCdTe provided the comparison involves the same base layer thicknesses (greater than the minority carrier diffusion length). The higher optimal doping of the superlattices relative to HgCdTe results in noise suppression. It is desirable because Auger recombination b substantially depressed. Shockley-Van Roosbroeck optical recombination and hence photon recycling is of little consequence in realistic device structures. © 1996 American Institute of Physics.
