研究目的
Investigating the resistive switching memory behavior based on assembled MoSe2 nanosphere arrays for potential applications in non-volatile memories and neuromorphic computing.
研究成果
The Ag/MoSe2/Au/Si device exhibits excellent bipolar resistive switching behavior, attributed to the formation and disruption of conducting filaments by moving metal ions on the nanospheres' surface. This suggests that nanosphere-assembled arrays can be used to fabricate high-performance resistive switching memory devices.
研究不足
The study focuses on the resistive switching behavior of MoSe2 nanospheres but does not explore the scalability of the device fabrication process or the long-term stability of the devices under operational conditions.
1：Experimental Design and Method Selection:
The study synthesized MoSe2 nanospheres using a hydrothermal method and prepared a resistive switching device with these nanospheres as the functional layer.
2：Sample Selection and Data Sources:
MoSe2 nanospheres were synthesized from Na2MoO4?2H2O and Se powder.
3：List of Experimental Equipment and Materials:
Stainless steel autoclave, DC magnetron-sputtering for Au thin film deposition, SEM and TEM for imaging, XRD for structural analysis.
4：Experimental Procedures and Operational Workflow:
The synthesis involved hydrothermal reaction at 200°C for 120 h, followed by device fabrication and electrical characterization.
5：Data Analysis Methods:
I-V characteristics were analyzed to study resistive switching behavior, with statistical analysis of set and reset voltages and currents.
