Physical and electrical properties of noncrystalline Al2O3 prepared by remote plasma enhanced chemical vapor deposition

Determination of Optical Properties in Germanium Carbon Coatings Deposited by Plasma Enhanced Chemical Vapor Deposition

In this research, Germanium-carbon coatings were deposited on ZnS substrates by plasma enhanced chemical vapor deposition (PECVD) using GeH4 and CH4 precursors. Optical parameters of the Ge1-xCx coating such as refractive index, Absorption coefficient, extinction coefficient and band gap were measured by the Swanepoel method based on the transmittance spectrum. The results showed that the refra...

Annealing and oxidation of silicon oxide films prepared by plasma-enhanced chemical vapor deposition

Comparison of Properties of Ti/TiN/TiCN/TiAlN Film Deposited by Cathodic Arc Physical Vapor and Plasma-assisted Chemical Vapor Deposition on Custom 450 Steel Substrates

This study investigated the effects of deposition techniques on the microstructural and tribological properties of Ti/TiN/TiCN/TiAlN multilayer coatings onto a Custom 450 steel substrate. The coatings were produced using cathodic arc physical vapor deposition (CAPVD) and plasma-assisted chemical vapor deposition (PACVD). The microstructural of the coatings was evaluated using (SEM), and phase f...

Nanocrystalline silicon quantum dots prepared by VHF plasma-enhanced chemical vapor deposition

Nanocrystalline silicon is a promising material for future ultralarge scale integrated circuits and display devices. Various methods have been demonstrated for the fabrication of nanocrystalline silicon with size less than 10nm. We have prepared nanocrystalline silicon ultrafine particles by very-high-frequency plasma decomposition of silane and hydrogen. Nanoparticles formed in the plasma cell...

Growth mechanism and properties of ZnO nanorods synthesized by plasma-enhanced chemical vapor deposition

Uniformly distributed ZnO nanorods have been grown by plasma-enhanced chemical vapor deposition using a two-step process. By controlling the oxygen content in the gas mixture during the nucleation and growth steps, no catalyst is required for the formation of ZnO nanorods. High-resolution transmission electron microscopy studies show that ZnO nanorods are single crystals and that they grow alon...
