Structural, Dielectric and Electric Properties of Manganese-Doped Barium Titanate
(Universiti Malaysia Perlis (UniMAP), 2018-10)
The Dielectric, Electric Properties and Microstructure of Ba Mnx Ti1-x O3 (where x = 0.0, 0.01, 0.02, 0.03, 0.04) ceramics have been investigated. The ceramic samples were prepared by Solid-State Reaction Method. The SEM ...
A New Technique for Measuring the Refractive Index
(Universiti Malaysia Perlis (UniMAP), 2018-10)
Refractive index is an essential optical parameter of materials. The operating principle of the refractometer is already known for more than hundred years. Refractometer measurement principally consists of analyzing an ...
Simulation and Analysis of a Silicon P-I-N Waveguide Based on Electro-Optic Carrier-Depletion Effect
(Universiti Malaysia Perlis (UniMAP), 2018-10)
This paper provides the analysis of a silicon P-I-N waveguide. The analysis is performed by simulating the said waveguide by applying the electro-optic carrier-depletion effect. Three design parameters have been altered, ...
Synthesis and Characterization of Polyvinyl alcohol /Polyaniline/Functionalized Multiwalled Carbon Nanotube Composite by Gamma Radiation Method
(Universiti Malaysia Perlis (UniMAP), 2018-10)
The composite of functionalized multiwalled carbon nanotube (f-MWCNT), polyvinylalcohol (PVA) and polyaniline (PANI) were in-situ synthesized by gamma () irradiation method. In order to make the free standing composite ...
Effective Index Method Applied on a GaN/InxGa1-XN Integrated Optics Waveguide
(Universiti Malaysia Perlis (UniMAP), 2018-07)
Effective index is a refractive index which depends not only on the wavelength but also on the mode in which the light propagates. It depends on the structural shape of the waveguide, mainly on its physical dimensions which ...
An Optimized Low‐Noise Low‐Power Preamplifier for Cardiac Implants
(Universiti Malaysia Perlis (UniMAP), 2018-04)
Among various analog circuits, the preamplifier has a prominent role in the analog front
end (AFE) circuit of biomedical implantable microsystems for a reliable acquiring of weak
biophysiological signals. The AFE acts ...
Synthesis and Characterization of Zinc Oxid Nanoparticles Using Green and Chemical Synthesis Techniques for Phenol Decontamination
(Universiti Malaysia Perlis (UniMAP), 2018-04)
Zinc oxide nanoparticles (ZnO-NPs) were successfully synthesized using both biological and chemical techniques. This study is mainly focused on the green synthesis (biological) method of ZnO-NPs using different plant leaf ...
A Survey on Emerging Technologies and Architectures of Low Power Preamplifiers for Biomedical Applications
(Universiti Malaysia Perlis (UniMAP), 2018-04)
Unlike other commercial devices, developing implantable microsystems for biomedical
applications requires critical analyses in terms of specifications, technologies, and design
techniques because of the devices’ safety ...
Enhancing the Electrical Properties of Porous Silicon Photodetector by Depositing MWCNTs
(Universiti Malaysia Perlis (UniMAP), 2018-07)
In the present work, multiwall carbon nanotubes (MWCNTs) layers dispersed in DMF and citric acid deposited by drop casting on porous silicon (PSi) photodetector have been prepared by electrochemical etching (ECE) process ...
Niobium Pentoxide Thin Film Prepared using Simple Colloidal Suspension for Optoelectronic Application
(Universiti Malaysia Perlis (UniMAP), 2018-04)
In this study, thin‐film microstructures of polymorphous niobium pentoxide were
successfully prepared at a low temperature. Spin coating was employed to deposit the
colloidal suspension before and after ultrasonic ...
