This paper reports on the preparation of nano-structured of MgxZn1-xO thin films by sol-gel spin coating method which will be used as a template layer to grow carbon nanotubes. The MgxZn1-xO films were deposited on Pt/Si (100) substrates. In this work, we focused on the effect of sol aging and Mg content on the film structure and resistivity. Sols with Mg content of x = 0.1, 0.3 and 0.5 were subjected...
This work presents the properties of nanocrystalline SiC(nc-SiC) films prepared by plasma enhanced chemical vapour deposition. A p-type silicon wafer with resistivity 2-7 Ωcm and (100) orientation was used as the substrate for the nc-SiC:H films. The concentration of species in the SiC films was determined by RBS and ERD. Chemical compositions were analyzed by IR spectroscopy. Film morphology was...
Transverse optical confinement in zinc oxide (ZnO) random cavities on Si substrate is achieved by a self-generated zinc silicate (Zn2SiO4) layer formed between the interface of ZnO and Si after thermal annealing.
Method of formation of regular PAA without a barrier layer in the process of anodizing of Al-film on n-type Si has been developed. Semiconductor InGaN-structures were selectively grown in modified PAA-template by MO VPE. Formed self-organized nanostructures InGaN have nonpolar crystallographic α-orientation. Investigations of luminescent properties and analysis of the spectral characteristics have...
Phosphorus doped ZnO quantum dots (QDs) have been fabricated on Si substrates by metal organic chemical vapor deposition method without using additional thermal activation processes. Single-crystal phosphorus doped ZnO quantum dots (QDs) have the average diameter of 20 nm and show preferred orientation with (001) direction. The incorporation of phosphorus in ZnO QDs was identified by x-ray photoelectron...
In this paper, ZnO nanorods were synthesized by the hydrothermal process on various substrates such as glass, ITO, p-type porous silicon and n-type porous silicon by dipping in ZnO solution and atomic layer deposition method. The thin films a grown on substrates were washed with deionized water to eliminate residual salts, dried in air, and annealed at 400 degC. Scanning electron microscopy and X-ray...
Inductive heating method was used to synthesis regular tetrapod-like zinc oxide within 1 minute in the air. The synthesis of the nanostructure was interpreted by the Vapor-Solid (VS) growth mechanism. The nanostructure was verified to be pure ZnO nanostructure by X-ray diffraction (XRD) spectrum. Field emission measurement was applied to prove that it owns low turn-on field and large emission current...
