Temperature Dependence of the Electric Conductivity of Silver-Silicon Monoxide Superlattices.

The dc resistance of synthetic silver-silicon monoxide superlattice structures has been measured as a function of temperature in the range from 77K to 300K. A new type of switching was discovered in which the electrical resistance changes abruptly from the room temperature value to a lower value at some threshold temperature. When the temperature is increased again, the sample switches at a high threshold temperature to a resistance value larger than the room temperature value, this higher value was found not to be stable; it decayed to the room temperature value within several hours. The identity period of the samples investigated ranged from about 20A to 300A. Each switching sample could be repeatedly and reproducibly cycled many times.
