    • Impact of hydrogen concentrations on the impedance spectroscopic behavior of Pd-sensitized ZnO nanorods 

      Muhammad Kashif, Muhammad Faroow; Md. Eaqub, Ali, Dr.; Syed Muhammad Usman, Ali Shah, Dr.; Uda, Hashim, Prof. Dr.; Sharifah Bee, O.A Abd Hamid, Prof. Dr. (Licensee Springer, 2013)
      ZnO nanorods were synthesized using a low-cost sol-gel spin coating technique. The synthesized nanorods were consisted of hexagonal phase having c-axis orientation. SEM images reflected perpendicular ZnO nanorods forming ...

    • Sol-gel synthesis of Pd doped ZnO nanorods for room temperature hydrogen sensing applications 

      Muhammad Kashif, Muhammad Faroow; Md. Eaqub, Ali, Dr.; Syed Muhammad Usman, Ali Shah, Dr.; Uda, Hashim, Prof. Dr. (Elsevier Ltd and Techna Group S.r.l., 2013-08)
      A sol-gel spin coating technique was described for the synthesis of Pd doped ZnO nanorods for hydrogen sensing applications. The nanorods were hexagonal in shape, 50-100 nm in diameter and uniform in distribution. They ...

    • 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 ...

    • Study of frequency dependent electrical properties of ZnO nanorods 

      Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr.; Syed Muhammad Usman, Ali Shah, Dr.; Zafar Hussain, Ibupoto; Willander, Magnus, Prof. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      Impedance spectroscopy is used to study the frequency dependent electrical parameters such as impedance, dielectric constant and conductivity of ZnO nanorods MSM structure in the range of 1 Hz to 10MHz under atmospheric ...

    • Study of ZnO thin film on silicon substrate by sol-gel spin coating method for bio-medical application 

      Foo, Kai Loong; Mohammad, Kashif; Uda, Hashim, Prof. Dr.; Syed Muhammad Usman, Ali Shah, Dr.; Willander, M., Prof. (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. ...
