Abstract
This work fabricates doping/un-doping poly-Si nanowire sensor with various lengths by using top-down technique for measuring salt concentration. Experimental results indicate that the resolution is proportional to the nanowire length and dopant concentration. But the sensitivity is inversely proportional to the length nanowire length. Moreover, the proposed sensor demonstrates 10 applications with similar current-time response and shows good repeatability.
