Abstract
InAs/InP quantum well structures were grown by low pressure metal organic chemical vapor deposition. During the growth, the As/P exchange reaction and As carryover were monitored in-situ by surface photoabsorption. We simulated the measured SPA signal using a multilayer model and effective medium theory to obtain the As compositional profile which was carried over into the InP layer.
