Efficient light upconversion via resonant exciton-exciton annihilation of dark excitons in few-layer transition metal dichalcogenides
Yi-Hsun Chen, Ping-Yuan Lo, Kyle W. Boschen +15
In this work, we report a pronounced light upconversion in few-layer transition metal dichalcogenides. Our joint theory-experiment study attributes the upconversion photoluminescen…

Unusual charge density wave introduced by Janus structure in monolayer vanadium dichalcogenides
Ziqiang Xu, Yan Shao, Chun Huang +16
As a fundamental structural feature, the symmetry of materials determines the exotic quantum properties in transition metal dichalcogenides (TMDs) with charge density wave (CDW). B…
