Quantum dots
Result description
This chapter focuses on quantum dots (QDs) embedded inside a semiconductor structure. It talks about metalorganic vapor phase epitaxy (MOVPE) QD preparation only. One can distinguish QD types according to growth modes, growth procedures, materials used, and structures with strain‐reducing layers, types of interfaces, and spatial arrangement of QDs (uncoordinated, array, and single/individual QDs). The three main growth technological procedures used for MOVPE preparation of QDs embedded in the structure are self‐assembled Stranski–Krastanov (SK) growth mode, formation of QDs in prepatterned inverted pyramids, and droplet epitaxy. The most widely used procedure is self‐assembling of QDs in SK growth mode. MOVPE growth parameters such as growth temperature, material type of precursors, reactor pressure, precursor flow ratio, total pressure and flow, complex purity of materials, precursors, and reactor setup can strongly influence the structure and device parameters, as well.n
