The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

we report a pronounced ∼6-fold enhancement of room-temperature A-exciton emission in a type-I MoSe₂/PdSe₂ van der Waals heterostructure, yielding a photoluminescence quantum yield of 6 %, compared to ∼1 % for as-exfoliated monolayer MoSe₂

C2weakest assumption

The observed enhancement and B-exciton quenching arise specifically from interlayer electronic coupling that redistributes exciton populations, rather than from fabrication-induced strain, defects, or dielectric changes at the interface.

C3one line summary

A MoSe2/PdSe2 heterostructure achieves six-fold higher A-exciton emission at room temperature via interlayer coupling that redirects excitons to the radiative channel.
