Abstract:
SiO2 thin films are deposited by radio frequency (RF) plasma-enhanced chemical vapor deposition (PECVD) technique using SiH4 and N2O as precursor gases. The stoichiometry of SiO2 thin films is determined by the X-ray photoelectron spectroscopy (XPS), and the optical constant n and k are obtained by using variable angle spectroscopic ellipsometer (VASE) in the spectral range 380–1600 nm. The refractive index and extinction coefficient of the deposited SiO2 thin films at 500 nm are 1.464 and 0.0069, respectively. The deposition rate of SiO2 thin films is controlled by changing the reaction press

Abstract:
Silicon nitride (Si3N4) materials are widely used in the electronics, optoelectronics, and semiconductor industries, with Si3N4 thin films exhibiting high densities, high dielectric constants, good insulation performance, and good thermal and chemical stability. However, direct deposition of Si3N4 thin films on glass can result in considerable tensile stress and cracking. In this study, magnetron sputtering was used to deposit a Si3N4 thin film on glass, and a silicon dioxide (SiO2) thin film was introduced to reduce the Si3N4 binding force and stress.

Amorphous Pb(Zr0.52Ti0.48)O3 (PZT) thin films were deposited on LNO/SiO2/Si and Pt/Ti/SiO2/Si substrates by a sol-gel method and then crystallized by microwave irradiation in the microwave magnetic field. The crystalline phases and microstructures as well as ferroelectric property of the PZT films were investigated, and the effect of substrate on crystallization of PZT thin films heated by microwave annealing was discussed. The PZT films on LNO/SiO2/Si substrate show a highly (100)-preferred orientation, and better ferroelectric property than those on Pt/Ti/SiO2/Si substrate. The results demon

SiO2 thin films are widely used in micro-electro-mechanical systems, integrated circuits and optical thin film devices. Tremendous efforts have been devoted to studying the preparation technology and optical properties of SiO2 thin films, but little attention has been paid to their mechanical properties. Herein, the surface morphology of the 500-nm-thick, 1000-nm-thick and 2000-nm-thick SiO2 thin films on the Si substrates was observed by atomic force microscopy. The hardnesses of the three SiO2 thin films with different thicknesses were investigated by nanoindentation technique, and the depen

The dielectric property of ZnFe2O4 – SiO2 composite thin films deposited on Pt - Ti -SiO2- Si substrates, prepared by sol-gel method, are investigated.

Such a composite structure exhibits a significantly enhanced dielectric constant with respect to SiO2 thin films without too large dielectric loss enhancement.

Porous silicon dioxide thin films were produced via dip-coating and doped with Ag+ by adding AgNO3 to the dipping solution. Nanoparticles were formed within the pores of these films by UV exposure. Nanoparticle formation was confirmed by UV-visible spectroscopy and Transmission Electron Microscopy (TEM). Conductive Atomic Force Microscopy (CAFM) showed that the conductivity of the films decreased upon exposure to UV. This decrease in the conductivity is most likely due to the clustering of charge carriers. Initially, Ag+ ions are attached to negatively charged pore walls in a dense packing net
