Abstract
Silicon nanowires (SiNWs) were synthesized by carbothermal evaporation technique from starting materials of silicon powder mixed with activated carbon. The evaporated silicon is carried by flowing inert gas and collected on Si(111) substrate. The results show that SiNWs were formed in groups are straight at some part and vertically at the other part with each group grew in the same direction. Overlapping in the growth direction produced another group of nanowires with crooked morphology.
