摘要

由于其独特的结构和优异的光电性能，二维材料及其异质结构是下一代光电技术的重要材料。光载流子的动态特性对这些材料的光电性能有重要影响。本文综述了近年来这些材料中光载流子动力学的研究进展。本文讨论了二维材料中载流子热化、能量弛豫、激子形成、激子-激子湮灭和激子复合的瞬态吸收测量。在空间领域，介绍了高空间分辨率瞬态吸收显微镜对光载流子平面内输运特性的研究。此外，还讨论了二维异质结构中的层间电荷和能量传递。

Research Progress on Photocarrier Dynamics in Two-dimensional Materials and Their Heterostructures

： Due to their unique structures and excellent optoelectronic properties ， two - dimensional （ 2D ） materials and their heterostructures are promising materials for the next generation optoelectronic technology. The dynamic properties of photocarriers have an important influence on the optoelectronic properties of these materials. This re⁃ view discusses the research progress in recent years on the photocarrier dynamics in these materials. In the time do⁃ main ， transient absorption measurements of carrier thermalization ， energy relaxation ， exciton formation ， exciton - ex⁃ citon annihilation ， and exciton recombination in 2D materials are discussed. In the spatial domain ， high - spatial - reso⁃ lution transient absorption microscopy studies of photocarrier in - plane transport properties are introduced. Further⁃ more ， interlayer charge and energy transfer in 2D heterostructures are discussed.

期刊介绍： Chinese Journal of Luminescence (CJL), supervised by Chinese Academy of Sciences (CAS), Sponsored by Committee on luminescence of Chinese Physical Society and Changchun Institute of Optics, Fine mechanics and Physics（CIOMP）of Chinese Academy of Sciences, is an authoritatively scientific and technical periodical of China in the field of luminescence, which is read widely in providing original papers and reviews that describe recent developments on basic theory and experimental studies of excited state processes and green lighting projects. The journal was established at 1980, and named after LUMINESCENCE AND DISPLAY, then renamed as CJL in 1986.
