Growth of III-V nanowires and nanowire heterostructures by metalorganic chemical vapor deposition
We have investigated the structural and optical properties of III-V nanowires, and axial and radial nanowire heterostructures, fabricated by metalorganic chemical vapor deposition. In addition to binary nanowires, such as GaAs, InAs, and InP, we have demonstrated ternary InGaAs and AlGaAs nanowires....

description | We have investigated the structural and optical properties of III-V nanowires, and axial and radial nanowire heterostructures, fabricated by metalorganic chemical vapor deposition. In addition to binary nanowires, such as GaAs, InAs, and InP, we have demonstrated ternary InGaAs and AlGaAs nanowires. Core-shell nanowires consisting of GaAs cores with AlGaAs shells, and core-multishell nanowires with alternating shells of AlGaAs and GaAs, exhibit strong photoluminescence. Axial segments of InGaAs have been incorporated within GaAs nanowires to form GaAs/InGaAs nanowire superlattices. We have developed a two-temperature growth procedure to optimize nanowire morphology. An initial high temperature step promotes nucleation and epitaxial growth of straight (111)B-oriented nanowires. Lower temperatures are employed subsequently, to minimise radial growth. © 2007 IEEE. |
