Photoemission tomography of excitons in 2D systems: momentum-space signatures of correlated electron-hole wave functions
Siegfried Kaidisch, Amir Kleiner, Sivan Refaely-Abramson +2
The momentum-space signatures of excitons can be experimentally accessed through time-resolved (pump-probe) photoelectron spectroscopy. In this work, we develop a computational fra…
Strain-induced exciton mobility in layered WS2 from first principles
Amir Kleiner, Sivan Refaely-Abramson
Exciton mobility in two-dimensional semiconductors is a key ingredient in materials-based design of optoelectronic functionalities. Monolayer transition metal dichalcogenides (TMDs…
Designable exciton mixing through layer alignment in WS-graphene heterostructures
Amir Kleiner, Daniel Hernangómez-Pérez, Sivan Refaely-Abramson
Optical properties of heterostructures composed of layered 2D materials, such as transition metal dichalcogenides (TMDs) and graphene, are broadly explored. Of particular interest…
Reduced absorption due to defect-localized interlayer excitons in transition metal dichalcogenide-graphene heterostructures
Daniel Hernangómez-Pérez, Amir Kleiner, Sivan Refaely-Abramson
Associating the presence of atomic vacancies to excited-state transport phenomena in two dimensional semiconductors is of emerging interest, and demands detailed understanding of t…
