This paper reports the invariance of the Meyer-Neldel Rule for thermally activated d. c. conduction under the aging effects in glassy Se (g-Se) and As₂Se₃ glass. For this purpose, we have analyzed the electrical data of the samples (i.e. glassy Se and As₂Se₃ glass) in bulk form. The fresh samples of both materials were prepared by the well-known melt-quench technique. Particularly, we have done current-voltage (I–V) measurements at different temperatures. Using the I–V characteristics, we calculated d. c. conductivity and the activation energy involved in d. c. conduction for both fresh as well as aged samples. Finally, we observed that the Meyer-Neldel rule holds and Meyer-Neldel characteristic energy are almost the same in both fresh and aged samples of g-Se as well as As₂Se₃ glass. This indicates that there is no time-dependent variation in the Meyer-Neldel parameter in the present chalcogenide glasses.

本文报道了玻璃态Se（g-Se）和As ₂ Se ₃玻璃在时效作用下热激活直流传导的Meyer-Neldel规则的不变性。为此，我们分析了样品的电学数据（例如玻璃态Se和As ₂ Se ₃玻璃）的散装形式。两种材料的新鲜样品都是通过众所周知的熔融淬火技术制备的。特别是，我们在不同温度下进行了电流-电压（IV）测量。利用I–V特性，我们计算了新鲜样品和老化样品的直流电导率和直流传导中涉及的活化能。最后，我们观察到在新鲜和老化的g-Se样品以及As ₂ Se ₃玻璃中，Meyer-Neldel规则成立并且Meyer-Neldel特征能量几乎相同。这表明在当前的硫族化物玻璃中，Meyer-Neldel参数没有随时间的变化。
