![عکس صفحه اول مقاله: Synthesis and characterization of amorphous SiOx nanowires prepared by vapor phase transport process Synthesis and characterization of amorphous SiOx nanowires prepared by vapor phase transport process](/preview/png/1646438.png)
Large quantities of amorphous SiOx nanowires have been synthesized by vapor phase transport process under atmospheric pressure in a horizontal furnace. The fabricated materials have been fully characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), energy dispersive X-ray analysis (EDX) and X-ray photoelectron spectroscopy (XPS). The nanowires have a typical length up to several tens of micrometers and a diameter in the range of 100 nm to 300 nm. The formation mechanism of the nanowires has also been discussed. The covering boats and the weight ratio of the raw materials were regarded to play an important role during the growth of the nanowires.
► The amorphous SiOx nanowires were synthesized by vapor phase transport process.
► The catalyst alloy was obtained by carbothermal reduction of Ga2O3 powders.
► The boats and the raw materials play important roles during the growth of the SiONWs.
