摘要: Abstract The surface and interface properties of self-ordered quantum well, wire dot GaAs/AlGaAs InGaAs/AlGaAs structures grown by low pressure organometallic chemical vapor deposition (OMCVD) on V-grooved substrates are described. Transmission electron microscopy as well cross sectional top atomic force in air employed to investigate the self ordering mechanisms these nanostructures. OMCVD patterned leads step-flow growth with monolayer steps oriented perpendicular grove edges nanofacets at bottom grooves. These ordered, surfaces form basis for formation AlGaAs InGaAs wells wires whose size shape determined composition conditions. V-groove reveal quasi-periodic facet undulations, suggesting dot-like providing three-dimensional confinement.
