    Microstructure and performances of ITO film prepared by ion beam sputtering

    by Ping C

    Composite Materials Research, Vol.6, No.3, pp. 6(3); , 2024; 467 Views, 7 PDF Downloads

    Ion beam sputtering deposition was firstly introduced to prepare indium tin oxide (ITO) film in this study. The ITO film was annealed at different temperature in a flow of nitrogen or air, respectively. The effect of annealing process on the microstructure, optical and electrical performances of the ITO film was studied. The results showed that the crystallinity and optical properties of the ITO film were improved with the increase of annealing temperature. The transmittance of the ITO film in visible regions increased up to 96% after it was annealed at 500℃ in nitrogen or in air. It was found that the resistivity of ITO film depended on both the annealing temperature and the annealing atmosphere, which showed a close relationship to the atomic percentage’s sum of oxygen vacancy and Sn 4+ , which was quantified by XPS result.

    Composite Materials Research, Vol.6, No.3, pp. 6(3); , 2024; 337 Views, 5 PDF Downloads

    Al/ lead monoxide (PbO) / p -Si structures were consructed to research the electrical properties of PbO interlayer and the conductance-voltage ( G-V ) and capacitance-voltage ( C-V ) characteristics of these structures at room temperature have been studied at 600kHz, 800kHz and 1MHz. The study of barrier height  , series resistance ( R s ) and interface states density ( D it ) using G-V and C-V graphs in these structures has been reported. G and C measurements were obtained to be dependent on frequency and bias voltage.

    Enhancement of photoelectrocatalysis efficiency of carbon nanotubes doped with TiO2 nanostructures applied on pesticide degradation

    by Ivana C

    Composite Materials Research, Vol.6, No.3, pp. 6(3); , 2024; 344 Views, 6 PDF Downloads

    In this study, a composite electrode based on multi-walled carbon nanotubes (MWCNT) and titanium dioxide (TiO2) prepared by the sol-gel method was synthesized and evaluated for the photoelectrochemical oxidation of carbaryl. The MWCNT/TiO2 composite was deposited into a titanium plate (Ti) and characterised by scanning electron microscopy (SEM), X-ray diffraction (XRD), and electrochemically. The photoelectrochemical oxidation of carbaryl was studied to evaluate potential applications of the Ti/MWCNT/TiO2 composite electrode in environmental science. The carbaryl removal efficiency yielded 71.0% at an applied potential of +1.5 V for 1 h using the Ti/MWCNT/TiO2 composite electrode in presence of light. In comparison, the removal efficiency reached 57.6% using the same parameters, however in absence of light. The results demonstrated the interesting photoelectrochemical properties of the developed material when applied on the pesticide degradation.

    Effect of Nano-particles on Energy Release Rate in Mode I Fracture Using Corrected Beam Theory

    by P Ghabezi

    Composite Materials Research, Vol.6, No.3, pp. 6(3); , 2024; 249 Views, 5 PDF Downloads

    The main objective of this paper is evaluation of nano-particles effect on energy release rate in nano-composites mode I fracture. Nano-composite samples with woven glass fibers and alumina nanoparticle have been fabricated using VARTM process as co-cured and underwent Double Cantilever Beam tests according to ASTM D5528 standard. To calculate the energy release rate in Mode I fracture, corrected beam theory data reduction scheme has been utilized for different percentage of nano particles.
