Buffer-Facilitated Epitaxial Growth of ZnO Nanowire

Abstract

This study introduces a new train of thought regarding the growth of well-arrayed nanowires. To reduce how defects such as grain boundary affect subsequent growth of the nanowires, the epitaxial buffer layer should be carefully chosen. The titanium nitride (TiN) buffer layer facilitates the growth not only of the arrays but also the epitaxy of zinc oxide (ZnO) nanowires, even given a lattice mismatch of up to 8.35% and the entirely different crystal structures between them.

Large-area and nanoscale n-ZnO/p-Si heterojunction photodetectors

“…The buffer seed layer facilitates subsequent growth of ZnO nanoneedles and controls the growth orientation of the film. [21][22][23][24][25] The thermal deposition setup unit (model 12A4D of HIND-VAC, India) was used for growing the layers of AZO followed by ZnO. The base pressure of vacuum chamber was maintained at 10 À3 mPa.…”

Facile microwave hydrothermal synthesis of zinc oxide one-dimensional nanostructure with three-dimensional morphology

“…For instance, solution-based synthesis [15][16][17][18][19][20][21], vapor phase growth [22][23][24][25][26][27][28][29][30][31] and template-assisted synthesis [32,33]. However, the introduction of metal catalyst, surfactants, or templates into the reaction system involves a complicated process, introduces heterogeneous impurities in the products, and increases the production cost, which may restrict the wide development of research and applications.…”

Laser Irradiance and Wavelength-Dependent Compositional Evolution of Inorganic ZnO and ZnOOH/Organic SDS Nanocomposite Material

“…7 It is transparent to most of the solar spectrum, therefore, widely used as window material in solar cells, optical waveguides, light modulators, and optical sensors. Application of ZnO has increased in current decades in the fabrication of switching elements, transistors, lasers, and detectors, and therefore controlled synthesis of good quality zinc oxide nanostructures such as nanocrystals, 8 nanowires, 9 nanobelts, 10 and other nanoarchitectures 11,12 has been in great demand. Several routes are employed for the production of ZnO nanomaterials including solvothermal, 13 thermal evaporation, 14,15 solid-state pyrolysis, 16 sol-gel synthesis, 17 sputtering, 18 chemical vapor deposition, 19 and molecular beam epitaxy, 20 etc.…”
