Abstract

High-density InGaAs/AlGaAs quantum wire (QWR) structures with a period of 430 nm were successfully grown by using constant metalorganic chemical vapor deposition growth technique in which submicron gratings were preserved even after an epitaxial growth of 1 μm thickness. The quantum confinement effect of the InGaAs/AlGaAs QWRs is strong due to the large band offset and enhanced migration of surface adsorbed III-group element species compared with the GaAs/AlGaAs QWRs. The photoluminescence signal of the InGaAs/AlGaAs QWRs was observed in the temperature range from 10 to 300 K with a relatively narrow full width at half maximum of <40 meV.
