Abstract:
Ag incorporation by photodissolution in Se-rich glasses results in a nano phase separated material with a Ge-rich germanium selenide glassy backbone and a distinct silver selenide mixed conducting phase and this leads to a number of interesting technological possibilities. For example, the ternary is a good solid electrolyte that will allow silver ion transport at room temperature. This solid electrolyte, in conjunction with a silver-containing anode, will support the electrodeposition of silver. The silver-rich regions formed by electrodeposition reduce the overall resistance of the electrolyte by bridging the high resistivity glassy regions and this reversible process is the basis of a novel solid state non-volatile memory device.
