Key Points

The study reveals a significant shift of up to 13.8% in the dispersion of phonon-polaritons in intercalated samples.
Using near-field nanoimaging, distinct behavior in the propagation of phonon-polaritons was observed with metal-ion intercalation.
Manipulation through metal-ion intercalation demonstrates a promising approach for tuning polariton characteristics.
The findings advance our understanding of phonon-polariton dynamics in van der waals materials, indicating potential applications.

Implication

Observational analysis shows changes in polariton propagation through metal-ion intercalation in α-MoO3, suggesting enhanced control of phonon-polaritons.

Abstract

Phonon-polaritons are manipulated by metal-ion intercalation of α-MoO 3 . Near-field nanoimaging reveals changes in polariton propagation behavior, including a shift in the dispersion of up to 13.8±1.7% in Sn-intercalated samples.
