Brief review on ZnO Synthesis methods, thin film & nanowire gas sensors
(Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)ZnO nanowires are ideal building blocks for a wide range of nanoscale electronics, optoelectronics, and chemical sensing devices. The material properties change when the material is in nanowire form as compare to thin film ... -
Effects of reaction time on the morphological, structural, and gas sensing properties of ZnO nanostructures
(Elsevier, 2014-02)Morphological transformation was achieved from ZnO hexagonal needle-like rods to hexagonal flower-like rods by varying the reaction growth time using the hydrothermal method. Optical bandgap energies were calculated from ... -
Performance of hexagon Au electrode on ZnO thin film schottky diode gas sensor
(International Frequency Sensor Association (IFSA), 2013)This paper presents an analysis of Schottky diode performance with the utilization of zinc oxide (ZnO) thin film as a gas sensor. The presented device is implemented with new type of electrode shape which is hexagon compared ... -
Sol-gel synthesis of ZnO nanorods for ultrasensitive detection of acetone
(American Scientific Publishers, 2013-12)ZnO nanorods were synthesized on low cost thermally oxidized silicon substrate using a simple and easily performable sol-gel spin coating technique followed by hydrothermal growth. C-axis orientation, good crystalline ... -
Structural and impedance spectroscopy study of Al-doped ZnO nanorods grown by sol-gel method
(Emerald Group Publishing Limited, 2012)Purpose – The purpose of this paper is to investigate the electrical transport mechanism of the Al-doped ZnO nanorods at different temperatures by employing impedance spectroscopy. Design/methodology/approach – Al-doped ... -
Study of ZnO thin film on silicon substrate by sol-gel spin coating method for bio-medical application
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)Transparent semiconductor ZnO thin films deposited on p-Si (100) substrates with different solvent (Methanol and Ethanol) were obtained by sol-gel method. The coated ZnO films were annealed in furnace at 500°C for 2 hours. ...
