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…
Guided Modes of Anisotropic van der Waals Materials Investigated by Near-Field Scanning Optical Microscopy
Daniel Wintz, Kundan Chaudhary, Ke Wang +11
Guided modes in anisotropic two-dimensional van der Waals materials are experimentally investigated and their refractive indices in visible wavelengths are extracted. Our method in…
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…
