Angular Emission Properties of Strained Transition-Metal Dichalcogenides
Lee Grimberg, Svyatoslav Kostyukovets, Moshe G. Harats
Monolayers of transition-metal dichalcogenides have shown that uniaxial strain changes both the photoluminescence emission energy and intensity. The changes are attributed to the b…
Limits of funneling efficiency in non-uniformly strained 2D semiconductors
Moshe G. Harats, Kirill I. Bolotin
Photoexcited electron-hole pairs (excitons) in transition metal dichalcogenides (TMDC) experience an effective force when these materials are non-uniformly strained. In the case of…
Neutral and charged excitons interplay in non-uniformly strain-engineered WS
Sviatoslav Kovalchuk, Moshe G. Harats, Guillermo López-Polín +3
We investigate the response of excitons in two-dimensional semiconductors subjected to controlled non-uniform strain fields. In our approach to non-uniform strain-engineering, a WS…
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…
Enhancement of two photon processes in quantum dots embedded in subwavelength metallic gratings
Moshe G. Harats, Ronen Rapaport, Adiel Zimran +2
We show a large enhancement of two-photon absorption processes in nanocrystal quantum dots and of light upconversion efficiency from the IR to the near-IR spectral regime, using a…
