    • 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 ...
    • Structural and morphological studies of cadmium sulfide nanostructures 

      Abdulwahab, S. Z. Lahewil; Yarub, Al-Douri, Assoc. Prof. Dr.; Uda, Hashim, Prof. Dr.; Naser Mahmoud, Ahmed, Dr. (Trans Tech Publications, 2013)
      Cadmium sulfide (CdS) nanostructures were prepared with different spin coating speed 1000 and 3000 rpm and molarities of Cd:S to be 1.2 to 0.01 mol/L using sol-gel spin coating technique. It is found that the average grain ...
    • Structural and optical properties of PbI2 nanostructures obtained using the thermal evaporation method 

      Safaa I. Mohammed; Yarub, Al-Douri, Assoc. Prof. Dr.; Uda, Hashim, Prof. Dr.; Naser Mahmoud, Ahmed, Dr.; R., Al-Gaashani (NRC Research Press, 2013-10)
      Lead iodide (PbI2) nanostructures were successfully prepared using the thermal evaporation method on a glass substrate at room temperature. The structural properties were analyzed using X-ray diffraction, which revealed ...
