摘要：
The real (E >) and imaginary (E > aEuro(3)) parts of complex dielectric permittivity and ac conductivity (sigma(ac)) of CdIn2S4 single crystals (cubic structure) have been measured in the frequency range f = 5 x 10(4) to 3.5 x 10(7) Hz. The results demonstrate that the dielectric dispersion in the crystals has a relaxation nature. In the frequency range f = 5 x 10(4) to 3.5 x 10(7) Hz, the ac conductivity of single-crystal CdIn2S4 follows the relation sigma(ac) similar to f (0.8), characteristic of hopping conduction through localized states near the Fermi level.
