研究目的
Investigating the potential of layered SnSe films fabricated by pulsed laser deposition (PLD) method as the functional layer of memristive electronic synapse with dual modes for neuromorphic computing.
研究成果
The study successfully demonstrated the integration of short-term plasticity (STP) and long-term plasticity (LTP) in a single layered SnSe-based device, suggesting its application potential in future neuromorphic computers. The scalable PLD method used in SnSe film fabrication indicates the industrial application potential of 2D materials.
研究不足
The study mentions the challenge of fabricating large-area layered two-dimensional films by scalable methods, which limits the industrial application potential of two-dimensional materials. The device-to-device variability is also noted as a limitation, suggesting that film uniformity needs to be further improved.
1：Experimental Design and Method Selection:
The study utilized a scalable pulsed laser deposition (PLD) method to fabricate large-area layered SnSe films. The films were then used as the functional layer of memristive electronic synapses.
2：Sample Selection and Data Sources:
The SnSe film was deposited on a commercially available Nb-doped STO(001) substrate.
3：List of Experimental Equipment and Materials:
A KrF excimer laser was used for PLD, and a magnetron sputtering system was used for depositing silver electrodes.
4：Experimental Procedures and Operational Workflow:
The SnSe film was characterized using X-ray diffraction (XRD), transmission electron microscope (TEM), atomic force microscope (AFM), and electrical performance was measured with an Arc One measurement instrument.
5：Data Analysis Methods:
Density functional theory (DFT) calculations were performed to evaluate the possibility of Sn-vacancy and Ag migrations in SnSe.
