Characteristics research of Cu-doped Programmable Metallization Cell

Cu를 도핑시킨 Programmable Metallization Cell의 특성연구

Programmable Metallization Cell (PMC) is a memory device based on the electrolytical characteristic of chalcogenide materials. In this study, we investigate the nature of thin films formed by photo doping of Cu ions into chalcogenide materials for use in solid electrolyte of programmable metallization cell devices. We were able to do more economical approach by using copper which play an electrolyte ions role. The results imply that a Cu-rich phase separates owing to the reaction of Cu with free atoms from chalcogenide materials.
