Popis: Crystalline thin films of NdNiO3 are known to exhibit characteristic metal-insulator electrical transitions. Infrared transmission measurements of these films have demonstrated the corresponding reversible optical switching response, transforming between IR-transparent and IR-opaque states. Their low-temperature transmission spectra exhibit a sharp increase in transmittance at an onset wavelength of approximately 3 mm (˜0.4eV), with an appearance suggesting formation of a distinct band gap structure. The transmission and reflection characteristics of these films differ significantly from those reported for bulk polycrystalline material.
