Description | ||||||
The effect of increasing GaP and InGaP Insertion layers thickness (0-4) monolayers (MLs) to improve the structural and optical properties of InP self-assembled quantum dots (SAQDs) on GaAs (001) substrate grown by metal-organic vapor phase epitaxy was reported . The growth of thin GaP and InGaP insertion layers between In0.49Ga0.51P buffer and InP QDs layer reduced the mean height and size fluctuation and increased the density of InP QDs. A maximum QDs density of 4.2 x 109 cm-2 and better and smaller QDs size and uniformity had been achieved at 2 ML GaP and InGaP insertion layers. The blueshift of the PL peak was enhanced by insertion of GaP and InGaP layers. Due to InGaP insertion layer, a more blue-shift of the PL peak emission was also observed. InGaP insertion layer led to better QDs quality and higher PL intensity compare to that of GaP insertion layer. | ||||||
