The influence of aluminium doping and oxygenation on the porperties of YBa₂Cu₃-ₓAlₓO₆.₅+δ (0≤x≥0.045) HTSC
(Universiti Malaysia Perlis, 2013)
The effect of Al₂O₃ particle addition on the crystal structure and superconducting properties of YBa₂Cu₃O₆.₅+δ (YBCO) ceramics is systematically studies. Samples were synthesized using a solid reaction to prepare YBa₂Cu₃O7-δ ...
Surface conductivity of aligned carbon nanotubes in silica gel
(Universiti Malaysia Perlis, 2013)
Carbon nanotubes (CNT) have attracted considerable attention since their discovery [1]. This is due to their unique physical properties and many potential applications. CNT have been investigated for possible application ...
Current voltage characteristics modeling of polycrystalline CdTe-CdS solar cell different grain-sizes of CdTe
(Universiti Malaysia Perlis, 2013)
A model is developed to explain the current-voltage (J-V) characteristics of polycrystalline CdTe-CdS solar cells with different grain sizes of CdTe. Analytical expressions are derived for J-V characteristics by solving ...
Comparsion of the physical properties for Cds and Cds doved PVA thin prepared by spray pyrolysis
(Universiti Malaysia Perlis, 2013)
Cadmium sulphide (CdS) and CdS doped with PVA semiconductor thin films were prepared by chemical pyrolysis technique. The thickness of the films was varied in the range (1.281, 1.367, 1.421, 1.485) μm and (1.722, 1.776, ...
Facile synthesis and characteristics of gold coated superparamagnetic iron oxide nanoparticles via sonication
(Universiti Malaysia Perlis, 2015)
We reported a simple protocol for synthesizing small-scale gold coated superparamagnetic iron oxide nanoparticles (SPION). The synthesis of the core-shell nanoparticles of the SPION-gold nanoparticles (GNP) was through ...
The impact of a mismatch on the interfacial stresses in NanoComposite
(Universiti Malaysia Perlis, 2014)
The study investigates the influence of the mismatch on the interfacial stresses in a nanofiber reinforced composite using finite element analysis (FEA). It is assumed that the mismatch exists between the nanofiber and the ...
Effect of Al doping on Band Gap of hexagonal cross section SiNWs
(Universiti Malaysia Perlis, 2014)
In this work band structure of hydrogen-passivated, free-standing silicon nanowires, oriented along [111] direction with hexagonal cross section was studied by using density functional theory using GGA approximation. Effect ...
Piezoelectrical properties for SnO₂ thin films prepared by spray pyrolysis method
(Universiti Malaysia Perlis, 2014)
Transparent conducting tin oxide (SnO₂) thin film has been deposited on glass substrate by spray pyrolysis technique. The spray pyrolysis technique using material tin chloride solution (SnCl4.5H2O) starts at different ...
Substrate temperature and background pressure effects on nanostructured zinc oxide thin films for thermoelectric applications
(Universiti Malaysia Perlis, 2015)
Zinc oxide (ZnO) thin films were grown on glass substrate by pulsed laser deposition (PLD) at different substrate temperature ranging from room temperature (RT) to 300ºC and various oxygen background pressures ranging from ...
Structural and optical properties of TiO₂ nanoparticles/PVA for different composites thin films
(Universiti Malaysia Perlis, 2016)
Polymeric films based on polyvinyl alcohol (PVA) doped with titanium dioxide nanoparticles at different weight percentage (1.25, 2.5, 5, 7.5, 10 TiO₂/PVA) were prepared using the sonification and casting techniques. The ...
