Abstract

AbstractWe report InP self-assembled quantum dots embedded in In0.51Al0.49P grown by metalorganic chemical vapor deposition. Growth parameters are altered to study the InP quantum-dot growth characteristics under various growth conditions. Quantum-dot morphology is characterized using atomic-force microscopy. Also, photoluminescence studies of the light-emitting properties are performed. Direct-bandgap ternary InxAlI−xP (x=˜0.7, ˜0.85) self-assembled quantum dots are also grown and compared with InP quantum dots.
