Nucleation Chronology and Electronic Properties of InAs1–xySbxPy Graded Composition Quantum Dots Grown on an InAs(100) Substrate

Abstract: We provide a detailed study of nucleation process, characterization, and electronic and optical properties of graded composition quantum dots (GCQDs) grown from the In-As-Sb-P composition liquid phase on an InAs(100) substrate in the Stranski–Krastanov growth mode. Our GCQDs exhibit diameters from 10 to 120 nm and heights from 2 to 20 nm with segregation profiles having a maximum Sb content of approximately 20% at the top and a maximum P content of approximately 15% at the bottom of the GCQDs so that hole conf… Show more
