研究目的
Investigating the sources of resistive switching in laser-fabricated graphene oxide memristors using numerical analysis tools.
研究成果
The study concludes that resistive switching in laser-fabricated graphene oxide memristors is due to the formation and destruction of a conductive filament, supporting the model of modified conductive path stoichiometry. This opens paths for device scaling with high precision laser scribing systems.
研究不足
The study is limited by the early stage of development of laser-fabricated graphene oxide memristor technology, including device variability and the need for advanced laser lithography tools for further scaling.
