Influence of Colloidal Au on the Growth of ZnO Nanostructures

Nanomaterials, 2021
Vapor-liquid-solid processes allow growing high-quality nanowires from a catalyst. An alternative to the conventional use of catalyst thin films, colloidal nanoparticles offer advantages not only in terms of cost, but also in terms of controlling the ...

Mechanical Properties of ZnO Nanowires

Physical Review Letters, 2008
Semiconductor nanowires are unique as functional building blocks in nanoscale electrical and electromechanical devices. Here, we report on the mechanical properties of ZnO nanowires that range in diameter from 18 to 304 nm. We demonstrate that in contrast to recent reports, Young's modulus is essentially independent of diameter and close to the bulk ...

Surface effects on the piezoelectricity of ZnO nanowires [PDF]

Journal of the Mechanics and Physics of Solids, 2013
We utilize classical molecular dynamics to study surface effects on the piezoelectric properties of ZnO nanowires as calculated under uniaxial loading. An important point to our work is that we have utilized two types of surface treatments, those of charge compensation and surface passivation, to eliminate the polarization divergence that otherwise ...

Performance improvement of miniaturized ZnO nanowire accelerometer fabricated by refresh hydrothermal synthesis [PDF]

Royal Society Open Science, 2017
Miniaturized accelerometers are necessary for evaluating the performance of small devices, such as haptics, robotics and simulators. In this study, we fabricated miniaturized accelerometers using well-aligned ZnO nanowires.

Graphitic platform for self-catalysed InAs nanowires growth by molecular beam epitaxy [PDF]

, 2014
We report the self-catalysed growth of InAs nanowires (NWs) on graphite thin films using molecular beam epitaxy via a droplet-assisted technique. Through optimising metal droplets, we obtained vertically aligned InAs NWs with highly uniform diameter ...

Efficient nitrogen incorporation in ZnO nanowires [PDF]

Scientific Reports, 2015
AbstractOne-dimensional ZnO nanowires (NWs) are a promising materials system for a variety of applications. Utilization of ZnO, however, requires a good understanding and control of material properties that are largely affected by intrinsic defects and contaminants.

Identification and characteristics of ZnO/MgO core-shell nanowires

AIP Advances, 2015
In this paper, ZnO/MgO core-shell nanowires are synthesized based on a one-step chemical vapor deposition (CVD) method. The scanning electron microscopy (SEM) images of core-shell nanowires indicate that Mg addition has little influence on the morphology
