Optical synaptic devices (OSDs) have neuromorphic vision sensing capability showing great potential in breaking the von Neumann bottleneck and facilitating future artificial vision systems. However, the applications of two-dimensional (2D) material-based OSDs are still impeded by complicated structures, preparation techniques and so on. In this work, we propose a 2D OSD based on BiSe films prepared by a chemical vapor deposition method followed by an in-situ thermal treatment.

- Research on 2D materials like bismuth oxyselenide (BiOSe) has increased due to its impressive properties such as high carrier mobility, air stability, and tunable band gap, making it suitable for advanced electronic and optoelectronic devices.
- The review covers BiOSe's crystal structure, methods to modify its physical properties, and synthesizing high-quality 2D BiOSe, while also exploring its applications in field-effect transistors, photodetectors, and neuromorphic computing.
- The potential of combining BiOSe with other materials to create heterostructures is highlighted, along with discussions on its future development and the challenges that need to be overcome for commercial use.
