Low-temperature infrared dielectric function of hyperbolic $α$ -quartz

Christopher J. Winta, Martin Wolf, Alexander Paarmann

We report the infrared dielectric properties of $α$ -quartz in the temperature range from $1.5 K$ to $200 K$ . Using an infrared free-electron laser, far-infrared…

Controlling the Infrared Dielectric Function through Atomic-Scale Heterostructures

Daniel C. Ratchford, Christopher J. Winta, Ioannis Chatzakis +20

Surface phonon polaritons (SPhPs) - the surface-bound electromagnetic modes of a polar material resulting from the coupling of light with optic phonons - offer immense technologica…

Second-harmonic phonon spectroscopy of $α$ -quartz

Christopher J. Winta, Sandy Gewinner, Wieland Schöllkopf +2

We demonstrate midinfrared second-harmonic generation as a highly sensitive phonon spectroscopy technique that we exemplify using $α$ -quartz (SiO $_{2}$ ) as a model system. A midinfra…
