Dielectric relaxation studies in Se₉₀Cd₈Sb₂ glassy alloy

Se₉₀Cd₈Sb₂ chalcogenide semiconducting alloy was prepared by melt quench technique. The prepared glassy alloy has been characterized by techniques such as scanning electron microscopy (SEM) and energy dispersive X-ray (EDAX).Dielectric properties of Se₉₀Cd₈Sb₂ chalcogenide semiconductor have been studied using impedance spectroscopic technique in the frequency range 5×10²Hz - 1×10⁵Hz and in temperature range 303-318K. It is found that dielectric constant ε′ and dielectric loss factor ε″ are dependent on frequency and temperature.
