The growth mechanisms of InAs / GaAs submonolayer (SML) structures for the growth control of quantum well island (QWI) structures have been investigated. Samples with different number of SML stacks of InAs are prepared by MBE and studied by RHEED, AFM and PL. The shape of the QWI structures have been observed to change with the number of SML stacks, which has been tentatively attributed to the transition in the growth processes as the strain is accumulated.
