Characterisation, analysis and optical properties of nanostructure ZnO using the sol-gel method
(Institution of Engineering and Technology (IET), 2012-02)Nanostructure ZnO was grown on thin aluminium layer, deposited on silicon substrate using the sol-gel method. The surface morphologies of nanostructure ZnO at different precursor concentrations were studied using scanning ... -
Correlation between the calcination and sintering temperature on phase formation, microstructure and dielectric properties of SrTiO3 ceramics
(Universiti Malaysia Perlis (UniMAP), 2022-10)The aim of this work is to investigate the effect of calcination temperature (600, 700 and 800°C) and sintering temperature (1000, 1050 and 1100°C) on pure phase formation, microstructure and dielectric properties of ... -
Fabrication of cobalt ferrite nanoparticles with a facile approach: Variations in structural, dielectric and morphological properties by influence of annealing temperature
(Universiti Malaysia Perlis (UniMAP), 2022-01)Spinel ferrites have a significant impact due to its physical and chemical properties. The sol-gel route has been employed in the present work, for achieving single phase nano-crystalline cobalt ferrites. All these samples ... -
Optical characterization of SixGe1-x films grown on nanostructured Si substrates
(Institute of Electrical and Electronics Engineers Inc., 2014-10-15)High quality Ge and SixGe1-x films grown on Si substrates are attractive for a wide range of applications in optics, optoelectronics, and high efficiency solar cells. In this study, heteroepitaxial growth of Ge on ... -
Organic thin film transistor memories with carbon nanodots fabricated by focused ion beam chemical vapor deposition
(American Institute of Physics, 2009-06-01)Metal-insulator-semiconductor field effect transistor (MISFET) structures with a nanocrystal carbon (nc-C) embedded in SiO2 thin films using a focused ion beam chemical vapor deposition (FIBCVD) system with a precursor of ... -
Structural, optical properties and Raman Spectroscopy of In2O3 Doped LiTaO3 thin films
(Universiti Malaysia Perlis (UniMAP), 2022-01)In this experiment, undoped, 2 wt.%, 4 wt.% and 6 wt.% In2O3 doped LiTaO3 thin films were successfully prepared by utilizing a spin coater to carry out chemical solution deposition on the substrate surface (CSD method). ... -
A study on the effect of calcination temperature on the graphitization of carbon nanotubes synthesized by the decomposition of methane
(Trans Tech Publications, 2014)The effect of calcination temperature for Fe2O3/MgO catalysts on the formation of carbon nanotubes (CNTs) was examined. CNTs were synthesized over Fe2O3/MgO catalysts calcined at different temperatures by catalytic ...
