    • Effects of reaction time on the morphological, structural, and gas sensing properties of ZnO nanostructures 

      Shahid, Hussain; Tianmo, Liu; Muhammad Kashif, Muhammad Faroow; Lin, Liyang; Wu, Shufang; Weiwei, Guo; Wen, Zeng; Uda, Hashim, Prof. Dr. (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 ...

    • Morphology and optical investigations of ZnO pyramids and nanoflakes for optoelectronic applications 

      N. K., Hassan; M. Roslan, Hashim; Yarub, Al - Douri (Elsevier, 2014-06)
      Zinc-oxide (ZnO) pyramidal and nanoflakes were grown by electrochemical deposition of Zn(NO3)2·6H2O on n-type Si substrate with different crystallographic orientations and on indium tin oxide (ITO)-coated glass. Various ...

    • Performance of hexagon Au electrode on ZnO thin film schottky diode gas sensor 

      Mas Elyza, Mohd Azol; Mahnaz, Shafiei, Dr.; Loew,  Pei Ling, Dr.; Foo, Kai Loong; Uda, Hashim, Prof. Dr.; Rashidah @ Siti Saedah, Arsat, Dr. (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 

      Muhammad Kashif, Muhammad Faroow; Md. Eaqub, Ali, Dr.; Syed Muhammad Usman, Ali Shah, Dr.; Foo, Kai Loong; Uda, Hashim, Prof. Dr.; Willander, Magnus (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 ...
