Fast anion-conduction in oxynitrides: oxygen and nitrogen transport in (Y, Zr)-(O, N)

Fast anion-conduction in oxynitrides: oxygen and nitrogen transport in (Y, Zr)-(O, N)

Cation doped zirconium oxynitrides (for example zirconium oxide doped with yttrium oxide and nitrogen, \'YZrON\'), having a fluorite-based structure, are suggested to have fairly high nitrogen diffusivity, besides their high oxygen mobility. In the present work, the tracer-diffusion of nit...
