Exciton fine structure in twisted transition metal dichalcogenide heterostructures
Sudipta Kundu, Tomer Amit, H. R. Krishnamurthy +2
Moiré superlattices of transition metal dichalcogenide (TMD) heterostructures give rise to rich excitonic phenomena associated with the interlayer twist angle and induced changes i…
Charge quenching at defect states in transition metal dichalcogenide-graphene van der Waals heterobilayers
Daniel Hernangómez-Pérez, Andrea Donarini, Sivan Refaely-Abramson
We study the dynamical properties of point-like defects, represented by monoatomic chalcogen vacancies, in WS-graphene and MoS-graphene heterobilayers. Employing a multidis…
Phonon-induced exciton weak localization in two-dimensional semiconductors
M. M. Glazov, Z. A. Iakovlev, S. Refaely-Abramson
We study theoretically the contribution of quantum effects to the exciton diffusion coefficient in atomically thin crystals. It is related to the weak localization caused by the in…
Spin-defect characteristics of single sulfur vacancies in monolayer
Alexander Hötger, Tomer Amit, Julian Klein +15
Single spin defects in 2D transition-metal dichalcogenides are natural spin-photon interfaces for quantum applications. Here we report high-field magneto-photoluminescence spectros…
Tunable magneto-optical properties in MoS via defect-induced exciton transitions
Tomer Amit, Daniel Hernangómez-Pérez, Galit Cohen +2
The presence of chalcogen vacancies in monolayer transition metal dichalcogenides (TMDs) leads to excitons with mixed localized-delocalized character and to reduced valley selectiv…
Mixed excitonic nature in water-oxidized BiVO surfaces with defects
Rachel Steinitz-Eliyahu, Daniel Hernangómez-Pérez, Franziska S. Hegner +3
BiVO is a promising photocatalyst for efficient water oxidation, with surface reactivity determined by the structure of active catalytic sites. Surface oxidation in the presenc…
