text: Phonon polaritons—light coupled to lattice vibrations—in polar van der Waals
crystals are promising candidates for controlling the flow of energy on the nanoscale
due to their strong field confinement, anisotropic propagation and ultra-long
lifetime in the picosecond range1,2,3,4,5. However, the lack of tunability of
their narrow and material-specific spectral range—the Reststrahlen band—severely
limits their technological implementation. Here, we demonstrate that intercalation
of Na atoms in the van der Waals semiconductor α-V2O5 enables a broad spectral
shift of Reststrahlen bands, and that the phonon polaritons excited show ultra-low
losses (lifetime of 4 ± 1 ps), similar to phonon polaritons in a non-intercalated
crystal (lifetime of 6 ± 1 ps). We expect our intercalation method to be applicable
to other van der Waals crystals, opening the door for the use of phonon polaritons
in broad spectral bands in the mid-infrared domain.
