    • Optical characterization of SixGe1-x films grown on nanostructured Si substrates 

      Ayu Wazira, Azhari; Adnan K Shafeeque, Ali; Kamaruzzaman, Sopian; Saleem Hussain, Zaidi; Uda, Hashim (Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
      High quality Ge and SixGe1-x films grown on Si substrates are attractive for a wide range of applications in optics, optoelectronics, and high efficiency solar cells. In this study, heteroepitaxial growth of Ge on ...

    • Role of micro and nanostructures in enhancing near IR optical absorption in Silicon 

      Cheow Siu, Leong; Ayu Wazira, Azhari; Kamaruzzaman, Sopian; Saleem Hussain, Zaidi (Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
      Role of micro and nanostructures in enhancing IR transmission in Si wafers has been investigated. Based on feature dimensions, incident light interaction can be described in terms of: (a) geometrical optics for wavelengths ...

    • Synthesis and characterization of self-assembled, high aspect ratio nm-scale columnar silicon structures 

      Ayu Wazira, Azhari; Boon Tong, Goh; Suhaila, Sapeai; Mohd Khairunaz; Kamaruzzaman, Sopian; Saleem Hussain, Zaidi (Institute of Electrical and Electronics Engineers Inc., 2013-06)
      The aim of this work is to synthesize nm-scale columnar structures in Si principally for solar cell applications. These structures are also desirable as templates for heteroepitaxial growth of SixGe1-x. A nanostructured ...
