Abstract Temperature and frequency dependent ac conductivity studies are made for silver‐doped a‐As 2 S 3 . The temperature dependence of σ ac for the As 2 S 3 ‐Ag system can be well explained by correlated barrier hopping model. Numerical calculations agree well with the experimental results. The energy levels and the concentration of charged defects are also estimated for these materials.
