TL;DR: The spectral range of long-lived and confined phonon polaritons in a polar van der Waals crystal is shown to be tunable by intercalation of Na atoms, expanding their potential for nanophotonic applications in the mid-infrared domain.
Journal ArticleDOI
Twisted Nano-Optics: Manipulating Light at the Nanoscale with Twisted Phonon Polaritonic Slabs.

TL;DR: A new degree of freedom (twist angle) for controlling the propagation of polaritons at the nanoscale with potential for nano-imaging, (bio)-sensing, quantum applications and heat management is demonstrated.
Journal ArticleDOI

TL;DR: In this paper, a far-field polarized IR reflectance spectra acquired on a single thick flake of the biaxial van der Waals semiconductor α-phase molybdenum trioxide (α-MoO3 ) was used to derive the dielectric function of the material.
Journal ArticleDOI

TL;DR: It is demonstrated that strain fields exerted by the piezoelectric device can be used to tune the energy of localized excitons in WSe2 up to 18 meV in a reversible manner, while leaving the single photon purity unaffected over a wide range.
