“…This requires a clear understanding of thin films fabrication, surface properties of the substrate as well as the chemistry and physical processes involved in the synthesis. Ghoranneviss et al [13] fabricated Cu-NP deposited on different substrates such as glass, Al 2 O 3 and SiO 2 and showed that uniform and nano-sized Cu nanoparticles can be produced on a lower-roughness substrate. Ulmeanu et al [14] have also described the self-assembly process of silica colloidal particles for substrate surfaces implying mica, glass, Ag and Au thin films.…”
