摘要：
This work provides the consequence of aging on the conduction mechanism of fresh as well as aged Se and As2Se3 chalcogenide glasses (ChGs). In this analysis, the sample synthesized by the melt-quench route was used as identical disk-shaped pellets for current–voltage (I–V) characteristics at different temperatures. Our observation shows the absence of space charge limited conduction (SCLC) for both fresh as well as aged samples of Se and As2Se3. The Poole–Frenkel conduction mechanism is detected as the leading model for fresh and aged samples of both Se and As2Se3 glasses. The activation energy is found to rise appreciably due to the aging effect of Se while almost constant for As2Se3 samples. The reason behind this may be the slight growth of crystallite due to aging in Se glass.
