Growth and application of group III-antimonides by MOVPE

There are a number of important considerations in common in the growth of InP/InGaAs and InAs/GaSb superlattices. These include: the uniformity of the periodicity within the superlattice, the type of interfaces and their arrangement within the superlattice and the abruptness of those interfaces. InAs/GaSb superlattices are a small sub-set of antimonide based semiconductors which are of interest to those studying solid state physics and designing devices with infrared applications. This paper will highlight the growth, by MOVPE, of some InAs/GaSb superlattices, and compare this with published results from the growth of InGaAs/InP superlattices, particularly with respect to the issues mentioned above.
