Abstract

ABSTRACTIn the present case, we have reported the temperature dependence of ac conductivity for bulk samples of glassy Se90In10−xAgx (x = 0, 2, 4, 6, 8) at different frequencies. In certain temperature range, ac conductivity is found to increase exponentially with temperature. From these measurements activation energy and pre-exponential factor are calculated. It is found that pre-exponential factor does not remain constant but varies with activation energy. This verifies the validity of MN rule. The experiment has been carried out in the temperature range 289–402 K and frequency range 20–500 kHz.
玻璃态Se90In10 - xAgx交流电导率MN规律的观察
在本研究中,我们报道了不同频率下Se90In10−xAgx (x = 0,2,4,6,8)玻璃样品的交流电导率的温度依赖性。在一定温度范围内,交流电导率随温度呈指数增长。根据这些测量结果计算了活化能和指前因子。指数前因子不是恒定的,而是随活化能的变化而变化。验证了MN规则的有效性。实验温度范围为289 ~ 402k,频率范围为20 ~ 500khz。
