The electrical conductivity in a metal-polymer-nanocrystalline metal system
has been investigated as a function of temperature. It is found that this
system undergoes a transition to the high-conductivity state at temperature
s of structural transformations in nanocrystalline electrodes. The results
are interpreted within the model of charge instability that arises in thin
polymer films under changes of the boundary conditions. (C) 2000 MAIK "Nauk
