【 摘 要 】

In general, the conductivity in chalcogenide glasses at higher tempratures is dominated by band conduction (DC conduction). But, at lower tempratures, hoping conduction dominates over band conduction. A study at lower temprature can, eventually, provide useful information about the conduction mechanism and the defect states in the material. Therefore, the study of electrical properties of Ge𝑥Se100-𝑥 in the lower temperature region (room temperature) is interesting. Temperature and frequency dependence of Ge𝑥Se100-𝑥 (𝑥 = 15, 20 and 25) have been studied over different range of temperatures and frequencies. Am agreement between experimental and theoretical results suggested that the behaviour of germanium selenium system (Ge𝑥Se100-𝑥) have been successfully explained by correlated barrier hopping (CBH) model.
