Abstract

Strands of nanometer-sized silver particles have been grown at the glass-crystal interface of a suitable glass-ceramic system. The samples exhibit high values of dielectric constant of the order of 500 at temperatures in the range of 80 to 200 K. This is believed to arise due to the Gorkov–Eliashberg anomaly. Above 200 K, a dielectric dispersion is observed, which is explained on the basis of a diagonal-layer heterogeneous conductor model.
