Moir & eacute; superlattices in van-der-Waals heterostructures offer a versatile platform for exploring emergent quantum phenomena. In type-I MoSe2-WS2 moir & eacute; superlattices, the large lattice mismatch ensures robustness of the moir & eacute; period against twist-angle disorder. The excitonic ground state is formed by moir & eacute;-trapped MoSe2 intralayer excitons. However, a key challenge is the controlled transfer of excitonic energy across moir & eacute; sites. This work investigates gate-controlled phonon-assisted resonant energy transfer (RET) as a means to transfer excitonic energy between moir & eacute; cells. By harnessing the interplay between resonantly excited moir & eacute; excitonic complexes and single or few phonons, energy transfer pathways can be modulated via the charging state of moir & eacute; cells. We discuss two potential RET mechanisms: phonon-assisted resonant tunneling and F & ouml;rster-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.
