Ta<sub>2</sub>N<sub>3</sub> nanocrystals grown in Al<sub>2</sub>O<sub>3</sub> thin layers
Abstract
<jats:p>Tantalum nitride nanoparticles (NPs) and cubic bixbyite-type Ta<jats:sub>2</jats:sub>N<jats:sub>3</jats:sub> nanocrystals (NCs) were grown in (Ta–N+Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>)/Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> periodic multilayers (MLs) after thermal treatment. The MLs were prepared by magnetron deposition at room temperature and characterized using grazing incidence small-angle X-ray scattering (GISAXS), X-ray reflectivity (XRR), grazing incidence X-ray diffraction (GIXRD), secondary ion mass spectrometry (SIMS) and X-ray photoelectron spectroscopy (XPS). We found amorphous tantalum nitride NPs at 600–800 °C, with a high degree of ordering along the surface normal and short-range ordering within the layers containing tantalum (metallic layers). At an even higher annealing temperature of 900 °C the NPs crystallize in the rare and relatively unexplored Ta<jats:sub>2</jats:sub>N<jats:sub>3</jats:sub> phase. However, the environment, morphology and spatial ordering of the NCs depend on the thickness of the metallic layers. For 12 nm thick metallic layers, the Ta<jats:sub>2</jats:sub>N<jats:sub>3</jats:sub> NCs have an average diameter of 6 nm and they are confined and short-range ordered within the metallic layers. When the metallic layers are thinner, the NCs grow over 20 nm in diameter, show no spatial ordering, while the periodic structure of the ML was completely destroyed. The results presented here demonstrate a self-assembly process of tantalum nitride NPs, the morphological properties of which depend on the preparation conditions. This can be used as a generic procedure to realize highly tunable and designable optical properties of thin films containing transition-metal nitride nanocrystals.</jats:p>
