    • Characteristics of nanostructure silicon photodiode using laser assisted etching 

      Ahmed, Naser M.; Yarub, Al-Douri, Assoc. Prof. Dr.; Alwan, Alwan M.; Jabbar, Allaa A.; Arif, Ghassan E. (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      We prepared nanostructures silicon photodiode (nPSi) by using laser assisted etching at fixed current density (30 mA/cm2) with different etching wavelengths of laser diode (532,650 and 810 nm), a (metal/nanostructure ...

    • Effect of roughness of hypo-and hyper-eutectic Al-Si piston alloy on wear characteristics under lubrication 

      Riyadh A., Al-Samarai; Haftirman, Dr.; Khairel Rafezi, Ahmad, Dr.; Yarub, Al-Douri, Dr. (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      The tribological behavior of tow AlSi alloys under the influence of surface roughness average was investigated for the present study. The silicon content of these alloys ranged 10 and 16-wt% Si, and includes hypoeutectic ...

    • Optical properties of GaN nanostructures for optoelectronic applications 

      Yarub, Al-Douri, Prof. Dr. (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      Electrochemical deposition method is used to prepare GaN nanostructure. The morphological studies using scanning electron microscopy (SEM), photoluminescence (PL) the refractive index and optical dielectric constant are ...
