摘要：

The performance of two-dimensional (2D) material–based devices is critically governed by their surface and interfacial structural characteristics. Precise characterization and engineering of these surfaces and interfaces are essential for the development of high-performance 2D functional devices.

This presentation focuses on the study and modulation of surface and interface structures in 2D materials, with aim of constructing novel neuromorphic synapses and exploring their applications in artificial neural networks. Specifically, the talk will cover: (i) quantitative characterization of surface adsorption behaviors using enhanced Raman spectroscopy; (ii) localized surface and interface engineering to achieve high-performance synaptic devices and scalable arrays; and (iii) the synergistic integration of multiple strategies to develop novel optoelectronic synaptic devices and arrays, with demonstrated applications in device authentication and anti-counterfeiting.
