Thermal treatment of samples has shown that the amount of blue-shift depends not only on the dielectric capping material but also on the semiconductor capping material over the QW structure. It has been shown that a SiNx dielectric capping layer induces larger blue-shift of bandgap than a SiO2 capping layer for any semiconductor capping layer. For the semiconductor capping layer, it has been shown that an InP capping layer induced the largest blue-shift of bandgap and an InGaAs capping layer induced the smallest blue-shift of bandgap. The combination of dielectric-semiconductor capping condition has been proposed in order to obtain the largest differential bandgap shift spatially.
