제목 Current conduction mechanism of non-volatile memory fabricated with Au nano-crystal embedded in poly(N-vinylcarbazole) layer
초록 Recently, organic non-volatile memories have been developed as a next generation of non-volatile memory because of nano-meter device-feature size and nano-second access and store-time. Memory effect in organic molecules is based on electrical bi-stability of the materials and the bi-stable phenomenon is observed in poly(N-vinylcarbazole) layer containing many small discrete Au islands. For the current conduction, at low field, it is followed thermally activated charge transfer. And, at high field, the space-charge field due to the stored charge in Au islands inhibits further charge injection from the electrodes so that we can find a negative-differential resistance. So, we’ll show that the switching phenomenon observed in the device conforms to the thermal activation and charge storage mechanism.
