摘要：
Heavily Sn-doped In(2)O(3)nano-pyramids with a Sn percentage of 19.97% by weight have been prepared by sputtering technique. The nano-pyramids with smooth facets and a sharp tip have been achieved by deposition on Sn-metal particles, leading to a diameter of similar to 100nm. The gas sensors realized from these pyramids are highly sensitive to ethanol gas, and the sensitivity is about 133.99 against 200ppm ethanol at 250 degrees C. Good sensitivity characteristics have been obtained even at a low temperature of down to 50 degrees C. The high response and low working temperature demonstrate the potential application of heavily Sn-doped In2O3 nano-pyramids for fabricating gas sensors. (C) 2018 Author(s).
