Electron and hole g-factors in two-dimensional Ruddlesden-Popper perovskites vary systematically with the number of inorganic layers and break the universal bulk pattern.

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

A systematic evolution of the electron and hole g-factors with decreasing layer thickness, which deviates from the universal bulk behavior and reveals confinement-driven trends similar to those observed in perovskite nanocrystals.

C2weakest assumption

That the observed Zeeman splittings in spin-flip Raman scattering and Kerr rotation can be cleanly assigned to electron and hole contributions without significant mixing from exciton or phonon effects or from the specific choice of excitation energy (section on experimental methods implied in abstract).

C3one line summary

Layer-dependent g-factors of electrons, holes, and excitons in (PEA)2MA(n-1)Pb(n)I(3n+1) perovskites deviate from bulk universal trends and match empirical tight-binding calculations.
