Three different surface variations are employed: i.e. polished Si, Si micropyramids and Si nanopillars profiles. A simple metal-assisted chemical etching method is used to fabricate the Si nanopillars, with Ag acting as a catalyst. Following deposition, substrates are subjected to post-deposition thermal annealing at 1000o C to improve the crystallinity of the Ge layer. Optical and morphological studies of surface area are conducted using field emission scanning electron microscopy (FE-SEM), Energy Dispersive X-ray (EDX), Raman spectroscopy and infrared spectroscopy. From the infrared spectroscopy analysis, the energy bandgap for Si-Ge films is estimated to be around 0.94 eV. This high-quality Si-Ge film is most favourable for optics, optoelectronics and high-efficiency solar cell applications. 2016-03-21T11:26:19Z 2016-03-21T11:26:19Z 2015 Article Malaysian Journal of Analytical Sciences, vol.19 (6), 2015, pages 1229-1242 1394-2506 http://www.ukm.my/mjas/v19_n6/pdf/AyuWazira_19_6_11.pdf http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41175 en Faculty of Science and Technology, Universiti Kebangsaan Malaysia
