Abstract
Disclosed are a ferrocene-containing conductive polymer, an organic memory device using the conductive polymer and a method for fabricating the organic memory device. The conductive polymer may include a fluorenyl repeating unit, a thienyl repeating unit and a diarylferrocenyl repeating unit. The organic memory device may possess the advantages of rapid switching time, decreased operating voltage, decreased fabrication costs and increased reliability. Based on these advantages, the organic memory device may be used as a highly integrated, large-capacity memory device.
