Quasi-steady electron-excitonic complexes coupling in a two-dimensional semiconductor
Shangkun Mo, Hao Zhong, Keming Zhao +10
Excitons and their complexes govern optical-related behaviors in semiconductors. Here, using angle-resolved photoemission spectroscopy (ARPES), we have elucidated the light-matter…
