    • Electrode design and planar uniformity of anodically etched small area porous silicon 

      Ahmed, N. M.; Zaliman, Sauli, Prof. Madya; Uda, Hashim, Prof. Dr.; Zul Azhar, Zahid Jamal, Prof. Dr. (American Institute of Physics, 2009-06-01)
      Porous silicon layer microstructure is sensitive to many parameters, which need to be controlled during etching. These include not only anodization time, current density, applied potential and electrolyte composition but ...
    • Pressure effect on Si quantum-dot potential 

      Yarub K. A., Al-Douri; Uda, Hashim, Prof. Dr.; Ahmed, N. M.; Zaliman, Sauli, Prof. Madya (American Institute of Physics, 2009-06-01)
      Application study of the quantum dot potential as a function of hydrostatic pressure for Si has been presented. This study has been calculated by means of our recent model using empirical pseudopotential method. The effect ...
    • A review on the electrochemical sensors and biosensors composed of nanogaps as sensing material 

      Dhahi, T. H. S.; Uda, Hashim, Prof. Dr.; Ahmed, N. M.; Mat Taib, A. (National Institute of Research and Development for Optoelectronics, 2010)
      In the past two decades, the biological and medical fields have seen great advances in the development of biosensors and biochips capable of characterizing and quantifying biomolecules.To understand the important relationship ...
    • Structural, morphological and optical studies of CdS nanostructures 

      Abdulwahab, S. Z. Lahewil; Yarub Al-Douri, Dr.; Uda, Hashim, Prof. Dr.; Ahmed, N. M. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      Cadmium sulfide (CdS) thin films of nanostructure were prepared with Cd:S (1.2 to 0.05 mol/L) and different spin coating speed (1000 and 5000 rpm) using sol-gel spin coating technique. Structural, morphological and ...
