Analysis of an electrically induced optical waveguide in a-axis barium titanate thin film
Arif Mawardi, Ismail; Prabakaran, Poopalan; Nurjuliana, Juhari; Mohd Azarulsani, Md. Azidin (Universiti Malaysia Perlis (UniMAP), 2021-12)In this paper, we report our analysis of an electrically generated optical waveguide in a 𝑐- axis barium titanate (BTO) thin film. The waveguide consists of a BTO thin film which is sandwiched between two electrodes. ... -
Correlation between the chemical composition and the conduction mechanism of barium strontium titanate thin films
Saif, Ala'eddin A.; Prabakaran, Poopalan (Elsevier B.V., 2011-06-30)Sol-gel barium strontium titanate thin films with different barium-to-strontium (Ba:Sr) values have been fabricated as MFM configurations. The Perovskite phase for the films is confirmed via XRD. In order to correlate the ... -
Design and fabrication of Microfluidic devices: MOSFET & Capacitor
Osman, R. A.; Esa, S. R.; Prabakaran, Poopalan (Institute of Electrical and Electronics Engineers (IEEE), 2006)Microfluidic devices, based on silicon, are fabricated by photolithography, wet chemical etching with focus on an liquid conduction channel n-channel depletion MOSFET and a silica-liquid dielectric capacitor. Masks for ... -
High-sensitivity pressure sensor using a polymer-embedded FBG
H., Ahmad; S. W., Harun; W. Y., Chong; M. Z., Zulkifli; M. M. M., Thant; Z., Yusof; Prabakaran, Poopalan (Wiley Periodicals, Inc., 2008-01)A new pressure sensor based on fiber Bragg gratings (FBG), is described with high-pressure sensitivity. The sensor is configured by embedding the FBG in a polymer-field aluminum casing with an opening on one side, which ... -
Sol-gel synthesis and characterization of Ba1-xGdxTiO3+δ thin films on SiO2/Si substrates using spin-coating technique
Teh, Yen Chin; Ala’eddin, A. Saif; Prabakaran, Poopalan (Kaunas University of Technology (Lithuania), 2017)Ba1-xGdxTiO3+δ, at x = 0, 0.05, 0.1, 0.15, 0.2, (BGT) thin films have been fabricated on SiO2/Si substrate using sol-gel method. The microstructure and surface morphology of the fabricated films have been investigated ... -
Surface plasmon resonance sensor sensitivity enhancement using gold-dielectric material
Fouad, S.; Naseer, Sabri; Zul Azhar, Zahid Jamal; Prabakaran, Poopalan (Universiti Malaysia Perlis (UniMAP), 2017)There has been increasing interest in the field of surface plasmon resonance sensing technology according to its advantages such as the small amount of sensing samples required, freedom of electromagnetic interference ...
