Figure 3From: Dramatically enhanced non-Ohmic properties and maximum stored energy density in ceramic-metal nanocomposites: CaCu3Ti4O12/Au nanoparticlesThe dependence of Au volume fraction on ϵ′ at RT for CCTO/Au nanocomposites. The symbols and solid curve represent the experimental data and the fitted curve, respectively. Insets 1 and 2 show the frequency dependence of ϵ′ at RT and tanδ (at 1 kHz and RT) of CCTO/Au nanocomposites.Back to article page
