초록

In this Study, the capacitance-voltage properties of the (Sr$\_$1-x/$.$Ca$\_$x/)$\_$m/TiO$_3$(0.05$\leq$x$\leq$0.2, m=0.996, 1, 1.004) ceramics were investigated. The results of the capacitance-voltage measurements indicated that the grain boundary was composed of the continuous insulating layers. The capacitance is almost unchanged below about 20[V] but it decreases slowly about 20[V]. The thick of the effective depleation layer was calculated by using the average grain size, it was in the range of 760∼3400[${\AA}$].
