HIGHLIGHTS
- who: Kai-Qiang Lin from the (UNIVERSITY) have published the research: High-lying valley-polarized trions in 2D semiconductors, in the Journal: (JOURNAL) of 29/04/2022
- what: The authors report the observation of tightly bound, valley-polarized, UVemissive trions in monolayer TMDC transistors: quasipArticles composed of an electron from a high-lying conduction band with negative effective mass, a hole from the first valence band, and an additional charge from a band-edge state. Nature Communications | 13:6980 Here, the authors demonstrate experimentally and theoretically that such high-lying trions with negative-mass electrons . . .
