In situ functionalization of graphene
Kyrylo Greben, Sviatoslav Kovalchuk, Ana M. Valencia +7
While the basal plane of graphene is inert, defects in it are centers of chemical activity. An attractive application of such defects is towards controlled functionalization of gra…

Intrinsic and Extrinsic Defect-related Excitons in TMDCs
Kyrylo Greben, Sonakshi Arora, Moshe G. Harats +1
We investigate an excitonic peak appearing in low-temperature photoluminescence of monolayer transition metal dichalcogenides (TMDCs), which is commonly associated with defects and…

Dynamics and efficient conversion of excitons to trions in non-uniformly strained monolayer WS
Moshe G. Harats, Jan N. Kirchhof, Mengxiong Qiao +2
We investigate the transport of excitons and trions in monolayer semiconductor WS subjected to controlled non-uniform mechanical strain. We actively control and tune the strain…
