Abstract
The atomic structure and the chemistry of basal‐plane inversion boundaries in Sb2O3‐doped ZnO were investigated using quantitative transmission electron microscopy techniques. Electron microdiffraction and high‐resolution transmission electron microscopy were used to determine the orientation of the polar c‐axis on both sides of the inversion boundary and the translation state between the inverted ZnO domains. Quantitative energy‐dispersive X‐ray spectroscopy combined with high‐resolution transmission electron microscopy allowed us to determine the exact amount and the arrangement of antimony in the boundary layer. Inversion boundaries are head‐to‐head oriented with a displacement vector of the oxygen sublattice of RIB=⅓[01[Onemacr]0] – 0.102[0001]. The boundary plane consists of a highly ordered SbZn2 monolayer in which the cations occupy the octahedral interstices of the structure. In the octahedral boundary layer, zinc and antimony atoms constitute a honeycomb superstructure with a threefold (3m) in‐plane symmetry.
