摘要：
Indium tin oxide (ITO) thin films were fabricated by magnetron sputtering in the mixture of argon and oxygen. Nitrogen doping was achieved by a two-step annealing process. It was found that with increasing temperature of the first-step treatment in N-2 atmosphere up to 800 degrees C, more nitrogen was doped into ITO thin films. After subsequent second-step annealing in air at 1200 degrees C, the ITO thin films had the most stable grain size and the highest content Sn4+ donors. This makes ITO thin film subjected to annealing in N-2 at 800 degrees C have the excellent resistance stability for high temperature (1200 degrees C) strain measurement. (C) 2018 Elsevier B.V.
