Abstract EN
The structural features and morphology of investigated Sb2S3 powder were analyzed by X-ray diffraction and scanning electron microscope techniques.
The dependence of dielectric properties and ac conductivity of bulk Sb2S3 as pellet on both of frequency (102–106 Hz) and temperature (303-393 K) were studied.
The dielectric constant (121.2-45.8) and dielectric loss (53.3-0.89) displayed noticeable dependence on frequency and in the investigated range of temperature 303-393 K.
The frequency dependence of ac conductivity σac(ω) follows up the power relation; σac(ω) = Gωs.
The frequency exponent s, diminished with the rise in temperature, implying that the correlated barrier hopping (CBH) is the predominant conduction mechanism.
The ac conductivity exhibited a thermally activated nature.
The localized states N(EF) values recorded in order of 1018 eV-1.
cm-3 at specific temperatures for frequency of 800 Hz.
Activation energy ΔE, calculated at different frequencies indicating a decrease from 117 meV to 89 meV with the increase in the frequency.
