Synthesis of nanopyramidal SnO2 by hydrothermal method on nanostructured silicon substrate with some study



In this study, we grew nanopyramidal SnO2 hydrothermally at low temperature on both bare and nanotextured silicon substrates. Plasma etching of silicon is accomplished for the evolution of nanotextures on silicon substrate which are called silicon nanograsses. Comparing Scanning Electron Microscope (SEM) images of the synthesized SnO2 nanopyramids on two bare and nanotextured silicon substrates, reveals that there are considerable differences between growth on these substrates such as better uniformity. Therefore, application of silicon nanograss substrates in the synthesis of SnO2 nanostructures can improve growth process and this promotes various applications of this material in the different science fields. We also survey the effect of seed layer on growth of SnO2 nanopyramid.
