Transport properties and polarization phenomena in intercalated Ag$_x$HfSe$_2$ compounds

The electrical properties of intercalated Ag$_x$HfSe$_2$ compounds ($x$ = 0.1, 0.2) have been investigated for the first time. Investigations have been performed using various current electrodes, which make it possible to pass either the electron current or the ion current across the sample. Polarization effects, which indicate the self-consistent migration of charge carriers in the samples, have been found for the samples at room temperature. Based on the characteristic features of polarization decay, coefficients of conjugated chemical diffusion have been evaluated.
