Abstract

The series of compounds H(Ca ₂Na _n-3Nb _nO _3n+1) form tetragonal perovskite-related layer structures that are strongly bound in two dimensions, but more weakly bound in the third. These materials can be delaminated by intercalating basic surfactant molecules into the layers, which spontaneously exfoliate the structure to form stable dispersions in a polar solvent. In this study, layers of exfoliated H(Ca ₂Nb ₃O ₁₀) material were examined in a Hitachi H9000NAR microscope equipped with a high angle electronic hollow cone unit. The data from the images indicate that coherent scattering can be important in hollow cone images from thin crystals when α ₁ ≤ 60 mrad.
