Table 4 Structural properties of the TNAs structures derived from XRD patterns using Rietveld refinement method and Williamson-Hall plot: a0, b0, c0 – lattice constants, V – relative volume crystalline phase contribution, <D> – diameter of coherently-diffracting domains (CDD), ε – relative deformation of a crystal lattice.
