Breaking refractive index records with layered van der Waals GeS2 for blue and near-ultraviolet photonics
GeS<sub>2</sub>, a layered a wide bandgap van der Waals material, is now found to exhibit record-high refractive index and extreme optical anisotropy across blue and near-ultraviolet bands, promising bright future for short-wavelength photonics.
