摘要：

The ionic conductivity of AgI films on tri-glycine sulfate (TGS) single crystal substrates was measured at temperature range from 300 K to 425 K. An enhancement of the ionic conductivity was observed in low temperature phase of AgI (beta-phase). The ionic conductivity of beta-AgI films shows an increase with decreasing the thickness. The conductivity enhancement is dominated by the ionic conduction at the interface between beta-AgI films and TGS substrates. Change of physical property of substrates. such as the phase transition and the variation of domain structure of TGS substrate, has no effect on the ionic conduction.
