Epitaxial Catalyst-Free Growth of InN Nanorods onc-Plane Sapphire
We report observation of catalyst-free hydride vapor phase epitaxy growth of InN nanorods. Characterization of the nanorods with transmission electron microscopy, and X-ray diffraction show that the nanorods are stoichiometric 2H-InN single crystals growing in the [0001] orientation. The InN rods are uniform, showing very little variation in both diameter and length. Surprisingly, the rods show...
متن کاملControlled synthesis of single-crystalline InN nanorods
Single-crystalline InN nanorods were successfully grown on c-Al2O3, GaN, Si(111), and Si(100) substrates by non-catalytic, template-free hydride metal–organic vapour phase epitaxy (H-MOVPE). It was evaluated thermodynamically and confirmed experimentally that the domain of nanorod growth lies in the vicinity of the growth–etch transition. Stable gas phase oligomer formation is suggested as the ...
متن کاملGrowth mechanism of catalyst- and template-free group III-nitride nanorods
A feasible mechanism for catalystand template-free group III-nitride nanorod growth by hydride vapor phase epitaxy (HVPE) is proposed. The mechanism is composed of random nanoparticle nucleation from growth conditions—growth temperature and Cl/group III ratio—based on the proposed mechanism, and the computed values showed good agreement with reported experimental results. The involvement of a g...
متن کاملStudy of InN epitaxial films and nanorods grown on GaN template by RF-MOMBE
This paper reports on high-quality InN materials prepared on a GaN template using radio-frequency metalorganic molecular beam epitaxy. We also discuss the structural and electro-optical properties of InN nanorods/films. The X-ray diffraction peaks of InN(0002) and InN(0004) were identified from their spectra, indicating that the (0001)-oriented hexagonal InN was epitaxially grown on the GaN tem...
متن کاملInN Nanorods and Epi-layers: Similarities and Differences
Transmission electron microscopy was applied to study InN nanorods grown on the a-, c-and r-plane of Al2O3, and (111) Si substrates by non-catalytic, template-free hydride metal-organic vapor phase epitaxy (H-MOVPE). Single crystal nanorod growth was obtained on all substrates. However, the shape of the nanorods varied depending on the substrate used. For example, nanorods grown on r-plane sapp...
