    • 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 ...

    • Nano-silver microcavity enhanced UV GaN light emitter 

      Naser Mahmoud, Ahmed; Zaliman, Sauli; Uda, Hashim; Zul Azhar, Zahid Jamal (Inderscience Enterprises Limited, 2009)
      We report results of measurements that help to clarify the role of silver in the reflection of UV emission light from GaN. A GaN as an active layer was sandwiched between two silver metal reflectors. GaN layer on sapphire ...
