2次元TR計測によるナノワイヤ群のジュール発熱による温度分布と通電経路の関係

抄録

In this study, we measured the temperature distributions of Ag nano-wire network (diameter 120-150nm) using thermoreflectance imaging method, when a constant current was supplied. As a result, the temperature change gave a non-uniform distribution following the current path based on the variation of the resistance at the wires and connections. Weibull distribution was applied to the probability distribution of the nano-wire temperature to analysis and evaluate the uniformity and connectivity of the wire. The results showed some potential of the shape factor of the Weibull distribution to represent the uniformity of the temperature distribution.
