Zusammenfassung

Moiré superlattices in van-der-Waals heterostructures offer a versatile platform for exploring emergent quantum phenomena. In type-I MoSe2-WS2 moiré superlattices, the large lattice mismatch ensures robustness of the moiré period against twist-angle disorder. The excitonic ground state is formed by moiré-trapped MoSe2 intralayer excitons. However, a key challenge is the controlled transfer of ...

Moiré superlattices in van-der-Waals heterostructures offer a versatile platform for exploring emergent quantum phenomena. In type-I MoSe2-WS2 moiré superlattices, the large lattice mismatch ensures robustness of the moiré period against twist-angle disorder. The excitonic ground state is formed by moiré-trapped MoSe2 intralayer excitons. However, a key challenge is the controlled transfer of excitonic energy across moiré sites. This work investigates gate-controlled phonon-assisted resonant energy transfer (RET) as a means to transfer excitonic energy between moiré cells. By harnessing the interplay between resonantly excited moiré excitonic complexes and single or few phonons, energy transfer pathways can be modulated via the charging state of moiré cells. We discuss two potential RET mechanisms: phonon-assisted resonant tunneling and Förster-like dipole–dipole transfer. Our findings highlight the potential of this approach for excitonic circuits and nanoscale energy transport, paving the way for future applications in quantum technologies.
