Unveiling Structural Disorders in Honeycomb Layered Oxide: $\mathrm{N}{\mathrm{a}}_2\mathrm{N}{\mathrm{i}}_2\mathrm{Te}{\mathrm{O}}_6$

Abstract

Honeycomb layered oxides have garnered tremendous research interest in a wide swath of disciplines owing not only to the myriad physicochemical properties they exhibit, but also their rich crystal structural versatility. Herein, a comprehensive crystallographic study of a sodium-based $\mathrm{N}{\mathrm{a}}_2\mathrm{N}{\mathrm{i}}_2\mathrm{Te}{\mathrm{O}}_6$ honeycomb layered oxide has been performed using atomic-resolution transmission electron microscopy, elucidating a plethora of atomic arrangement (stacking) disorders in the pristine material. Stacking disorders in the arrangement of honeycomb metal slab layers (stacking faults) occur predominantly perpendicular to the slabs with long-range coherence length and enlisting edge dislocations in some domains. Moreover, the periodic arrangement of the distribution of alkali atoms is altered by the occurrence of stacking faults. The multitude of disorders innate in $\mathrm{N}{\mathrm{a}}_2\mathrm{N}{\mathrm{i}}_2\mathrm{Te}{\mathrm{O}}_6$ envisage broad implications in the functionalities of related honeycomb layered oxide materials and hold promise in bolstering renewed interest in their material science.
