$Fe_2O_3$-$Bi_2O_3$ 소결체의 전기적 Switching 특성(II)

Electrical Switching Effects in the Sintered $Fe_2O_3$-$Bi_2O_3$ (II)

5Fe₂O₃-5Bi₂O₃소결체에서 V-I특성의 규격화, theramal current runaway의 인가 step 전압의 존성, current channel의 분석등을 연구하였다. 5Fe₂O₃-5Bi₂O₃소결체의 switching 특성의 측정으로부터 전기적 switching기구는 thermal ionic breakdown으로 설명된다.

Studies have been perfor mad on the normalization of V-I characteristics, the dependence of current runaway on the applied step voltage and the analysis of the current channet in the sintered 5Fe$_2$O$_3$-5Bi$_2$O$_3$. From the measurement of snitching Properties of the sintered 5Fe$_2$O$_3$-5Bi$_2$O$_3$, it is exe]twined that the electrical switching mechanism is that of thermal ionic breakolown.
