Production of large-area 2D materials for high-performance photodetectors by pulsed-laser deposition

Our review provides a comprehensive overview on the latest progress in pulsed-laser deposition (PLD) of 2D layered materials (2DLMs), and its application in photoelectric detection. We begin with a retrospective overview on various 2DLMs and their development in photoelectric detection. Then we present the fundamentals of PLD and its unique advantages compared with the traditional growth methods. Subsequently, the PLD growth of 2DLMs and the influence of various parameters are discussed. After this, we describe the current metal-semiconductor-metal and vertical heterojunction photodetectors that incorporate the PLD-grown 2DLMs. This leads into a summary of the strategies used to improve the photosensitivity and in-depth insights into the working mechanism. We then present the PLD-fabricated transparent and flexible 2DLM photodetectors. Finally, we highlight the unresolved issues and propose the future directions in this emerging research field.
