“…These result indicate that the concentration of silver plays an important role in the variation of dielectric parameters with temperature. This type of behavior has also been reported by various workers in chalcogenide glasses [11][12][13][14][15][16]. As the silver impurity is added to the a-Se-Te system, dielectric constant and dielectric loss decrease.…”

The eect of annealing at dierent temperatures between Tg and Tc on the AC conductivity and dielectric properties was studied for Se70Te15Bi15 lms grown by thermal evaporation technique. The lms were characterized by X-ray diraction, dierential thermal analysis, and energy dispersive X-ray spectroscopy. X-ray diraction analysis shows the occurrence of amorphous to polycrystalline transformation for lms annealed at annealing temperature Ta ≥ 473 K. AC conductivity σAC(ω) was studied as a function of Ta, frequencies (0.1100 kHz) and working temperatures (303393 K). It was found that σAC(ω) obeyed Aω s law. According to the values of s and its temperature dependence, the AC conduction mechanism was determined in terms of the correlated barrier hopping and quantum mechanical tunneling models for the as deposited and annealed lms, respectively. The DC and AC activation energies were determined as a function of Ta. Values of dielectric constant ε1 and dielectric loss ε2 were found to increase with increasing Ta. A Debye-like relaxation of dielectric behavior was observed for polycrystalline lms, and was found to be a thermally activated process.

“…Considerable attention has been given to chalcogenide glasses in recent years, mainly because of their wide range of applications in solid-state devices in both the scientific and industrial fields [1,2]. These glasses reveal distinct optical properties such as infrared (IR) transmission and electrical properties (such as threshold switching, memory switching, inorganic photoreceptors and IR transmission and detection through lenses and optical wave guides) that make them useful in several fields, e.g.…”

In this paper, we have studied the temperature and frequency dependence behavior of ac conductivity in the glassy system Se 80−x Te 20 Sn x (0 x 10). All the measurements have been carried out in the frequency range 1-500 kHz and in the temperature range from room temperature to the glass transition temperature T g . The density of defect states has been determined using the correlated barrier-hopping model for all these glassy alloys. The appearance of local extrema in the density of defect states is explained in terms of the change from one-dimensional (1D) to 2D structure (from 'bundles' to 'layers') and from 2D to 3D structure (from 'layers' to 'clusters').
