Abstract

Ag chalcogenide glasses

phase separation

Near field microscopy

conductivity

The combined investigation of electrical conductivity by complex impedance spectroscopy and microstructure by Electric Field Microscopy (EFM) helped us to characterize the electrical heterogeneousness existing in several Ag-Ge-S glasses. While the (Ag2S)x(GeS)60(GeS2)40-x glasses were shown to be homogeneous, (Ag2S)x(GeS2)100-x glasses show heterogeneousness. Such heterogeneousness is the electrical signature of a phase separation existing in the glasses. The obtained data helped in understanding the difference of 4-5 orders of magnitude in the conductivity of the system.
