黑磷半导体光物理及应用研究进展OA北大核心CSTPCD

Compared with other two-dimensional materials,two-dimensional black phosphorus(BP)has attracted extensive attention across various fields including transistors,photonics,optoelectronics,sensors,batteries and catalysis in recent years owing to its high carrier mobility,wide adjustable band gap,and in-plane anisotropy.However,the instability of black phosphorus in natural environmental conditions and the chanllenges in the fabrication of large-area,high-quality semiconducting black phosphorus nanostructures seriously have hampered its rapid development in the field of nanodevices,catalysis and biophotonics.In this work,we summarize the controlled fabrication and optical properties of highly stable BP nanostructures in recent years.The research advances in photoresponse applications,including photodetectors,nonlinear and linear photonics,photocatalysis and biophotonics,are highlighted.Additionally,the challenges and opportunities of BP nanostructures in future optoelectronic devices,photocatalysis and biophotonics are discussed.
