Selective excitation and imaging of ultraslow phonon polaritons in thin hexagonal boron nitride crystals
Antonio Ambrosio, Michele Tamagnone, Kundan Chaudhary +4
Polaritons in 2D and van der Waals (vdW) materials have been investigated in several recent works as an innovative platform for light-matter interaction, rich of new physical pheno…

Mechanical detection and imaging of hyperbolic phonon polaritons in hexagonal Boron Nitride
Antonio Ambrosio, Luis A. Jauregui, Siyan Dai +7
Mid-infrared nano-imaging and spectroscopy of two-dimensional (2D) materials have been limited so far to scattering-type Scanning Near-field Optical Microscopy (s-NSOM) experiments…
