THE FEATURES OF CONDUCTION ANISOTROPY OF INTERCALATED LAYERED (original) (raw)

The temperature dependence of conduction of the intercalated by silver layered relaxational TlInS2 ferroelectrics was investigated. It is shown, that in temperature range relaxational like behaviour of dielectric and polar properties of a crystal, the conduction is carried out by means of hops of charge carriers on the located states laying in a narrow energy strip near to a Fermi level. The energy of activation of extrinsic charge carriers is determined. The density of the located states, average lengths of charge carriers hops, a difference between energy states, concentration of deep traps is calculated. It is established, that doping of Ag+ ions in Van der Waals bond of TlInS2 results in reduction of conduction anisotropy.
