How does the vapour liquid solid (VLS) method proceed in producing nanowires? Correct Answer Source enters nanoclusters ➔ Saturation begins ➔ Solidification of source and outward growth from the nanocluster ➔ Source is turned off to adjust size
The vapour liquid solid(VLS) process requires liquid metal catalysts, a source material from laser ablated particles or a feed gas like silane. The process proceeds with the entrance of the source into the nanoclusters, followed by its saturation. Upon achieving supersaturation, solidification of the source occurs which the grows out of the nanocluster. Switching off the source helps in adjusting the length of the nanowires generated in the procedure.
