Vacancy-Engineered Phonon Polaritons in α-MoO3
We report on the phonon-polaritonic dispersion configurability in α-MoO 3 by thermomechanically engineered oxygen-vacancy defects. Near-field nanoimaging of hot-pressed α-MoO 3 shows phonon-polariton dispersion modulation up to 11.7%, with 5% vacancies allowing up to 15% dielectric permittivity modulation. .
