Silicon nanowires fabricated by thermal evaporation of silicon monoxide

Advances of SiOx and Si/SiOx Core-Shell Nanowires

“…Thermal evaporation of SiO powder is a process in which the oxides were found to play an important role in the nucleation and growth of nanowires (Niu et al, 2004, Pan et al, 2001. During annealing, SiO evaporates and transported by the carrier gas to the lower-temperature region to decompose on substrates.…”

“…As the silicon atoms increase, the nuclei will grow up into wires. In this growth route, some of the growth directions of the nanowires will be limited to <111> and <112> orientations due to oxide reaction and growth energy (Niu et al, 2004, Pan et al, 2001). …”
