Low-temperature infrared dielectric function of hyperbolic $\alpha$-quartz

Phys. Rev. B 99, 144308 (2019) We report the infrared dielectric properties of $\alpha$-quartz in the temperature range from $1.5\ \mathrm{K}$ to $200\ \mathrm{K}$. Using an infrared free-electron laser, far-infrared reflectivity spectra of a single crystal $y$-cut were acquired along both principal...
