Essentially, ZnO powder and silicon substrate were placed in upper and lower streams of a horizontal quartz tube, respectively and heated via a furnace up to 960 C for about 1 hour. During the heating process, evaporated ZnO vapour was transported to lower stream and deposited onto the substrate containing Au catalyst at constant pressure of 1 torr. The substrate tilt angles were chosen for 0∞ and 30∞ and argon flow rates between 1.1-5.0 sccm. Observation on FESEM/EDX and field emission results revealed the optimal growth of ZnO nanowires which occurred at an angle 30∞ and flow rate of 5 sccm. Parameters such as atom% of Zn and O and aspect ratio were measured and analysed. | Hot-tube thermal evaporation | ZnO Nanowires |Vapour-liquid-solid mechanismenHot-tube thermal evaporationZnO NanowiresVapour-liquid-solid mechanismArticle20120594
