Field emission (FE) is based on the physical phenomenon of quantum tunneling, in which
electrons are injected from the surface of materials into vacuum under the influence of an …

On integrating one-dimensional (1D) nanocrystals (nanowires) to useful devices, in this
review article, we provide a background on vapor-based growth processes and how they …

This paper presents a review of current research activities on ZnO nanorods (or nanowires).
We begin this paper with a variety of physical and chemical methods that have been used to …

Graphene-based nanocomposites are emerging as a new class of materials that hold
promise for many applications. In this paper, we present a general approach for the …

The electrical conductivity, structural and optical properties of ZnO nanostructured
semiconductor thin film prepared by sol–gel spin coating method have been investigated …

We report a study of the role of hexamine in the seeded growth of zinc oxide (ZnO)
nanowires by hydrothermal route. We show that the growth can be made highly anisotropic …

Well-aligned arrays of ZnO nanoneedles were fabricated using a simple vapor phase
growth. The diameters of the nanoneedle tips are as small as several nanometers, which is …

Copper-doped zinc oxide nanowires were fabricated on copper-coated silicon substrate by
sintering a mixture of zinc oxide and graphite powders at high temperature. Copper …

Nanostructural zinc oxide pins have been fabricated by vapor transport on copper-coated
silicon wafer. The nanopins are composed of hexagonal wurtzite-phase zinc oxide with …

ZnO nanoneedles were prepared on a silicon wafer through a chemical vapor deposition.
The diameters of the needle tips were in a range of 20–50 nm. High-resolution transmission …
