Abstract
Copper particles having diameters in the range 4.2-7.2 nm have been grown within a glass ceramic by subjecting the latter to an alkali/copper ion exchange reaction followed by a reduction treatment in hydrogen. A wide range of surface resistivity has been induced in the glass-ceramic samples by a change of the heat treatment schedule. The dc electrical resistance has been measured over the temperature range 80-300 K. These data when analyzed by Ziman's equation show that the effective Debye temperature decreases as the metal particle size is reduced.
