概要

• 論文の詳細を見る

• The dielectrie property was measured to observe growth of metallic clusters in Nb-Al_2O_3 sintered mixtures with Nb volume fraction f ranging from 0 to 0.15. As Nb clusters grow large, the effective dielectric constant ε^* (or capacitance) increases to diverge, reflecting the occurrence of the percolation transition at around f=0.15. The power law was found to hold for ε^* with a critical exponent of 0.6.
