ZnO Thin Films Growth by APCVD Using Zinc Acetate.

Hydrothermal Growth of ZnO Nanostructures Using Zinc Thin Films as Seed Layer

Zinc oxide nanostructure is selectively synthesized by a simple reaction of zinc acetate dehydrate. With hexamethyltetramine (HMT) under mild hydrothermal conditions, we use zinc thin films as seed layer. Scanning electron microscopy (SEM) result shows that zinc thin films were oxidized to hexagonal ZnO seeds in the absence of zinc salt and base under hydrothermal conditions. The effect of a mi...

Effect of zinc acetate concentration on the structural and optical properties of ZnO thin films deposited by Sol-Gel method

The transparent Zinc Oxide (ZnO) thin films were deposited by multi-step sol-gel method and the effect of sol concentration on structural, morphological and optical properties were investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to characterize structures and morphologies of the as-deposited films. The crystallographic orientation of the ZnO films show...

Characterization of ZnO Thin Films

ZnO is a strategic material for various photonic applications. We present our results on characterization of thin films of ZnO grown by sol-gel spin and RF sputtering methods. The characterization techniques involved ellipsometry, scanning electron microscopy with energy dispersive analysis, X-ray diffraction and scanning tunneling microscopy. Microstructural characterization of the films using...

Growth of vertically aligned ZnO nanorods using textured ZnO films

A hydrothermal method to grow vertical-aligned ZnO nanorod arrays on ZnO films obtained by atomic layer deposition (ALD) is presented. The growth of ZnO nanorods is studied as function of the crystallographic orientation of the ZnO films deposited on silicon (100) substrates. Different thicknesses of ZnO films around 40 to 180 nm were obtained and characterized before carrying out the growth pr...
