Abstract

The AgI systems containing various mol% of AgBr and CuI were synthesized. X-ray analyses revealed that all synthesized systems had face centered cubic structures. Using impedance analyzer, electrical conductivity measurements of these systems were carried out at temperatures from 20 to 200$^{\circ}C$. From this measurement, it was found that the activation energies of these systems were in the range 0.6∼0.7 eV and the system containing 5 mol% AgBr showed the highest conductivity and the smallest activity energy.

AgI(80 mol%)를 기질로 하여 AgBr 15 mol% + CuI 5mol%, AgBr 10 mol% + CuI 10mol%, AgBr 5 mol% + CuI 5mol%의 계를 제조하여 이들의 이온 전도성을 상온에서 200$^{\circ}C$까지 임피던스분석기(impedance analyzer)를 이용하여 측정한다. 이 온도영역에서 활성화에너지는 0.6∼0.7 eV를 얻을 수 있었으며, 5 mol% AgBr계의 이온 전도성이 가장 컸으며 활성화에너지는 가장 작음을 보였다.
