A Study of Dendritic Filament Growth in Tungsten Tri-oxide and Copper Electrolytes


Abstract ABSTRACT

Programmable metallization cell (PMC) technology uses the mechanism of metal ion transport in solid electrolytes and electrochemical redox reactions to form metallic electrodeposits. When a positive bias is applied from anode to cathode, atoms at the anode are oxidized to ions and dissolve in the solid electrolyte. They travel to the cathode under the influence of an electric field, where they are reduced to form electrodeposits. These electrodeposits are filamentary in nature and grow in different patterns. Devices that make use of the principle of filament growth have applications in memory, RF switching, and hardware security.

The solid electrolyte under investigation is tungsten trioxide with copper deposited on top. For... (more)
