AC electrical properties of Fe[In.sub.2][.sub.4]

The frequency and temperature dependences of the ac capacitance and resistivity of Fe[In.sub.2][S.sub.4] semiconductors are studied. Resonances are observed at certain temperatures in the frequency range (2.5-5.0) x [10.sup.5] Hz. The permittivity of the crystals and the activation energy of charge...

Zusammenfassung:The frequency and temperature dependences of the ac capacitance and resistivity of Fe[In.sub.2][S.sub.4] semiconductors are studied. Resonances are observed at certain temperatures in the frequency range (2.5-5.0) x [10.sup.5] Hz. The permittivity of the crystals and the activation energy of charge carriers are determined. It is found that electrical conduction in the given temperature interval is governed by an activation mechanism. The activation energy is frequency-dependent, because the relaxation time of barrier layers decreases with rising frequency. DOI: 10.1134/S1063784212040202
