Comments

Hexagonal boron nitride (h-BN). In-plane refractive index (ordinary ray, no). h-BN flakes of thickness around 1000 nm were mechanically exfoliated from a bulk crystal and transferred onto quartz substrates for transmission measurements. The single oscillator model is used to fit transmission spectra of several hBN flakes of different thickness.
