Abstract

The nanostructure of ferecrystals [(SnSe)_1+δ]_m [TSe₂]_n with T = Mo, Ta, synthesized by the modulated elemental reactants (MER) method with 1 ≤ m, n ≤ 30, was investigated by various methods of transmission and scanning transmission electron microscopy (TEM/STEM), including precession electron diffraction (PED). The influence of the layer composition, sequence, and thickness, on the resulting intergrowth structure and disorder is elucidated, including various aspects of intra- and inter-layer stacking disorder.
