    • Alternative-current electrochemical etching of uniform porous silicon for photodetector applications 

      Husnen R., Abd; Yarub, Al-Douri, Assoc. Prof. Dr.; Naser Mahmoud, Ahmed, Dr.; Uda, Hashim, Prof. Dr. (Electrochemical Science Group, 2013)
      The twining of alternative-current (AC) with electrochemical etching (ECE) to fabricate porous silicon (PS) is studied. The porosity percentage is obtained by gravimetric analysis. The effect of different current densities; ...

    • Influence of current density on porous silicon characteristics 

      Husnen R., Abd; Naser Mahmoud, Ahmed, Dr.; Yarub, Al-Douri, Assoc. Prof. Dr.; Uda, Hashim, Prof. Dr. (Trans Tech Publications, 2013)
      Porous silicon structures have been fabricated by electrochemical etching using different current density. From field emission scanning electron microscope images (FE-SEM) it was observed that more uniform distribution of ...

    • Investigated optical and elastic properties of Porous silicon: Theoretical study 

      Y., Al-Douri; N.M., Ahmed; N., Bouarissa; A, Bouhemadou (Elsevier Ltd., 2011-08)
      Compatibility between experimental and theoretical works is achieved. Empirical Pseudopotential Method (EPM) is used to calculate the energy gap of Si which is found to be indirect. Features such as refractive index, optical ...

    • New optical features to enhance solar cell performance based on porous silicon surfaces 

      A., Ramizy; Z., Hassan; K., Omar; Y., Al-Douri; M.A., Mahdi (Elsevier B.V., 2011-05)
      Electrochemical etching is used to fabricate porous silicon (PS) surfaces for both sides of the Si wafer. The effect of PS on performance of Si solar cells is investigated and the reflected mirrors are manipulated to enhance ...
